A nice article but I see a few flaws. First of all if the distribution of LEGO sizes/prices is increasingly skewed it is better to either split the sample or look at medians or rolling medians than averages. Secondly, this is a perfect case to run a regression panel regression with time dummies to see both the impact of time and the impact of size on the prices.
Ugh. Hey, congrats to everyone who wanted this, but do we really need another MP Prime? MP-10 is fantastic as it is, and it certainly looks better than this. MP-10’s only problem for me was the faux grille. If they made a new MP Prime that looked good and didn’t use a faux grille, then I would be interested. Instead it looks like none of the front uses any real truck parts; even the chest windows look different from the truck windows!

Refractor and Laser Prime were only available in a box set named "Chaos on Velocitron" that includes Dynamus and Quickswitch, Parsec and Autobot Nautica, Fastclash, and a Rodimus Prime Titan Master head. The set was officially announced by Hasbro to be a Toys"R"Us exclusive, and was sold at stores in the United States, Canada, and Hasbro's Asian markets (such as Malaysia, Singapore, and Hong Kong). Despite this, it later became available via Amazon in the United States (but not in Canada) as well, actually sold by Amazon directly (as compared to a third-party seller).

On Cybertron, Optimus Prime kicked back to do a little bit of paperwork and reminisce. With Shockwave defeated, Cybertron was enjoying a new era of peace. He was interrupted by Hot Rod, who reported that a group of "pesky humans with their peashooters" were giving an Autobot team on Earth a hard time. Prime suspected Cobra's involvement and counseled Hot Rod not to be so dismissive of the humans. The Art of War #1 When the team returned to Cybertron and mysteriously vanished in the Gladiator Zone, Prime was prepared to go search for them, but was convinced by Hot Rod to stay behind and organize a peace ceremony. The Art of War #2
What I find more interesting is who’s in this wave. Not only is there Hot Rod and Barricade in ’80s muscle car form, but Optimus Prime in his red G1 Peterbilt truck form (just with movie Optimus’ head! Maybe Bumblebee will explain the origin of his “rip off everyone’s face” fetish). Two versions of Bumblebee round out the wave, his traditional movie-verse Camaro and G1 VW Bug.
Part of the first wave of Bot Shots Series 1 launchers, this repaint of Optimus Prime comes with a large trailer that pops open to form a battle station with a spring-loaded launching platform. He appears to have the same plastic colors as the single release, and the same set of paint operations, but his paint is done in different shades, having glossy dark blue paint and glossy bright red paint. The black part of his launcher is sculpted to look vaguely like the repair done that is part of Generation 1 Optimus Prime's repair bay.

Inspired by the 1985 promotional version of Optimus Prime that featured Pepsi stickers on his trailer, this outlandish incarnation of Prime is a slightly altered version of Takara's 2005 Pepsi Convoy figure (which represented a different character to Prime). The figure was only sold by Hasbro Toy Shop at various conventions, and given away as a promotional prize by Pepsi, via their Mountain Dew brand.
This new smaller mold of Optimus Prime features a similar transformation to the original toy. Unlike most transformable figures in this line, Optimus completely lacks 5mm fist holes. Compared to the finalized toy, the product photo on the back of the box has a number of deco differences, most notably silver thighs and white accents above the front windows in addition to those below. The same box photo and the more deco-accurate stock photo (right) also neglect to fold out his fists, which is the only other step in his two-step transformation.

I you can get an official reissue for around the same price, do it. I lucked out and got an opened but mint Encore for $50 last week but you'll be getting lucky that way. All Hasbro reissues have short smokestacks and long stacks are harder to get separate to swap out. Average price for a Japanese reissue is around $100 opened. If you are on a budget and the kid doens't care about slight issues, the $40 KO would be the better option.

Two of his limbs are based on Armada Optimus Prime; one "normal" (Inferno helmet), one pre-Earth-body (Knock Out helmet). The main torso-bot is based on Generation 1 Optimus's original body. Another limb-bot is based on live-action Optimus (Soundwave helmet), and the remaining one (Ironhide helmet)... actually looks to be based on the Optimus-like-but-not-Optimus Micromaster Overload! The heck?

This mold was redecoed in 2000 as Car Robots Black Convoy, and slightly retooled as his US incarnation "Scourge". After Scourge, the next use of this mold was planned to be Toxitron, which ended up being canceled. The slightly retooled version of this mold was released in 2006 in Japan as reissue Battle Convoy, which was the name of this toy during the Japanese Generation 2. The reissue used the Robots in Disguise modified tooling, with a slightly modified deco using silver vacuum-metalized plastic on his chest and trailer sides along with additional paint applications and G2 symbols. The mold was also redecoed to create a new Generation 2 version of Ultra Magnus as an E-Hobby exclusive (unusual in that the character was killed in the course of Japan's Generation One fiction).
I don't have a really good pic and I probably have something more rare in a box somewhere that I can't remember but this is my fav 'rare' Transformer: https://s3.amazonaws.com/tf.images/reduced-image_4474_106.jpg Sorry I don't have a real pic, I am packing up to move but here is a stock pic of TF Prime FE Japanese Convention Exclusive Optimus Prime.

In robot mode, Voyager class Optimus Prime is proportionally more accurate to his CGI design than the leader class toy and has a more accurate headsculpt, but due to the aforementioned lessened complexity significant sacrifices had to be made, such as "cheats" to the transformation sequence, to achieve this and thus he is overall less accurate than he initially appears. In addition to previously mentioned changes, he carries much of the truck's front hood, grill and fenders on his back like a backpack. However, he maintains a superb level of articulation and posability.
Available exclusively from Japanese 7-11 stores, MP-711 is an Ultra Magnus-decoed Convoy—white with green and blue highlighting—themed with 7-Eleven logos. Unlike most MP-10 redecos, he comes with a trailer, Roller, and Spike figure, who is sporting a 7-Eleven uniform. Roller and the combat deck come with 7-Eleven logos, however Convoy's shoulder logos are stickers with the option of a green 7-Eleven logo or the standard Autobot logo on either shoulder.

Part of the first wave of the 2015 Robots in Disguise line, Optimus Prime is a smaller-scale toy. He transforms from robot to trailer/truck combination and back! Like every Robots in Disguise Legion Class toy, Optimus features 3mm posts on his hands and arms. Due to the size and simplified transformation, he ends up having 6 wheels instead of 10. His scannable Autobot insignia is on his robot mode left shoulder. However, the badge is completely impossible to scan in vehicle mode.

He was only available as an Amazon exclusive in the United States, but was also released at brick and mortar retails in Australia and Hasbro's Asian markets, such as Singapore. Oddly enough, even though the official press release for the figure identifies it as "14 of 30" in Hasbro's Thrilling 30 campaign, the packaging does not sport any such markings.[3] To complicate matters further, a later retrospective by Hasbro on Facebook identifies another product as "14 of 30", which doesn't sport any such markings on its packaging either.[4]
During the three-part "One Shall Rise", Optimus uses the Matrix of Leadership to defeat Unicron. Unfortunately, in doing so, he not only emptied the wisdom of the Primes, but lost his own memories as a Prime, believing himself to be Orion Pax once again. Megatron took advantage of this to manipulate Orion into deciphering Iacon records the Decepticons have stolen from Cybertron. Eventually, Orion figures out the truth and escapes. Jack is later able to restore Optimus' memories after downloading the wisdom of the Primes from Vector Sigma into its key which Optimus gave him before he left to stop Unicron. However, Optimus could not recall the time he spend as a Decepticon.
The "Underbite Jetpack Takedown" Optimus Kreon uses the new 2015 style of Kreon hips and torso, with a hollow hip-peg and a central post inside the torso for increased grip... which also makes them incompatible with about four years' worth of Kreons. Based on his appearance in Robots in Disguise, he features a new version of the Optimus helmet, this time lacking a moutplate. He attaches to an included jet pack, armed with two pressure-launch missiles.
This sculpt was redecoed by Takara into a golden Lucky Draw figure and later released in its original coloration with a trailer as a "Perfect Edition" (see below for both), while Hasbro would later redeco it into their Classics-branded "DVD Edition". The mold was also used to make Masterpiece Ultra Magnus and "Convoy Black Version", representing one of many drones built in Prime's image, rather than Prime himself.
Hot Rod is featured again in Maximum Dinobots. Returning to Earth to continue his search, Hot Rod arrived at the gates of the Machination's complex, and Scorponok prepared himself to deal with the intruder. Unfortunately, Hot Rod found himself fighting well out of his weight class as he was man handled by Scorponok, who cheerfully bashed his face in, put out one of his optics and snapped his leg. The Headmasters dragged him into Scorponok's control room where, with absolutely no prompting, the big man explained his entire plan for the Dynobots, Skywatch and the Machination. Hot Rod seemed less than impressed with this rather mundane approach, which ticked Scorponok off enough for him to point out that it was obviously just the first stage in his master plan. He was also warned to remain awed or he'd be of no further interest. When the Dynobots and newly arrived Monsterbots seemed to turn Scorponok's plan on its head, Hot Rod burst out laughing, at which point, Scorponok ordered him taken out and shot. In the lift to the surface, Hot Rod suddenly erupted in flames, killing his captors, but draining his power supply. Weakened and with a crippled leg, he collapsed on the floor.
The Transformers Animated series was broadcast internationally in 2008 except in Japan, where it aired in 2010. This new series uses a very different art-style from the previous series. The Autobots and Decepticons, while fighting in space for possession of the Allspark, crash-landed onto a futuristic Earth and resume their battle after laying dormant for years. In addition to the Decepticons, the Autobots have to face the human villains as well. Classic characters such as Optimus Prime, Bumblebee, Prowl, Starscream, Megatron, Jazz and Ultra Magnus appear in this series.

In the event that Windcharger successfully turned the Decepticons’ forcefield off, reinforcements burst into the base just as Megatron was strike Optimus from behind. A wayward shot from Megatron then revealed the location of the gravity gun to the Autobots. Optimus ordered his troops to charge the weapon. Hook caught Optimus in the gravity gun’s sights, and sent the Autobot leader floating upwards.

MP-10 Convoy, advertised as a "perfect new model" on its packaging, is an entirely new tooling of Generation 1 Optimus Prime. Convoy is now smaller, making him more in-scale with other recent Masterpiece toys, such as Rodimus, and comes with a trailer and various accessories. While the front of the vehicle mode's cab is an accurate depiction of a mid-to-late-1980s Freightliner FLT cabover, the back half, (which is, as usual, made out of Convoy's legs) is much larger and robot-leggier in proportion. (So much that they sculpt a ladder on each side.)
Only available at ToysЯUs, this Optimus Prime is a redeco of the Classics figure. He features a cartoon/toy accurate deco on his truck/robot parts, and vacuum-metallized upper legs & front grille to evoke his original Generation 1 toy. Like every Classics Optimus Prime mold, he still features all of his accessories. This Optimus was packaged along with the redecoed Age of Extinction Optimus Prime.
Optimus confronted his archenemy on the battlefield, though he had to knock Starscream aside to get to him first. Due to a nearby explosion that rocked the battlefield, Optimus nearly lost both his stance and his head when Megatron took advantage of the opening. But Optimus's quick reflexes allowed him to shift to vehicle mode and back, dodging Megatron's attack and striking back in the process. As the battle raged on, both combatants found themselves evenly matched. Then Ratchet contacted Optimus with dire news; the Decepticons had managed to abduct SARA! Fate

Optimus Prime was given the Matrix by Primus himself, and used to be friends with Megatron. Prowl is his closest friend and Ratchet is his oldest. Searching for Energon, the Autobots landed on Earth, but were followed by the Decepticons. With the help of their human allies, they bested their foes, and knowing they would return, decided to stay and wait to defend the planet once more. Optimus Prime was proud to be an Autobot. I Am Optimus Prime
Optimus Prime was subject to several molding and color variations in his early days. The earliest release of the figure featured larger fists, a gun with a thick, round barrel, a slightly-differently shaped gas pump, grey rockets, a grey Roller, a grey launcher in his Combat Deck, and metal plates in the floor of the Combat Deck (a holdover from the Diaclone version of the toy, to which the magnetic feet of the pilots could cling). In short order, his fists were slimmed down, the gun's barrel was pared down to a more slender form, the gas pump's shape was altered, the rockets and launcher were recast in black plastic, the metal plates were removed from the Combat Deck, and Roller's color was changed to a light blue. Along with Roller's color change, however, the Combat Deck's drone pod also became light blue, and a third running change soon followed that saw it restored to its original darker blue, and Roller changed along with it. These modified components would become the default accessories used by subsequent reissues of the Prime toy would take, though Roller stills fluctuates back and forth between grey and dark blue, depending on how show-accurate each reissue wants to be.
