The price of this piece is likely to reach the $300 range if the auction is indeed true: it is being listed as a TakaraTomy Lucky Draw. The problem with this type of situation is that information is vary limited. People could end up spending a boat-load of cash on a figure that is mass produced, or else they can “snag” a very rare item at a somewhat lower price than normal.
This is the type of thing that makes Transformers collecting really fun, that is if you have the cash to play the game. At least we know this is indeed a legit figure, just look at the copyright stamp below! Collecticon will follow this auction and let you know what happens. Photos are from Paranooid’s auction.
