Gold and Silver Power of the Force R2-D2 Coin Variations: This variation in the Artoo Detoo "Rebel Droid" Power of the Force coin has recently come to light, though its not certain exactly what circumstances are behind the change in color. Very likely, the gold version (the standard, aluminum POTF coin is also included in this image) represents the equivalent of the gold C3PO "Protocol Droid" coin, which itself made use of the POTF coin mold while being pressed in a new color. Its possible that the presence of the Death Star and an X-wing fighter - two vehicles that would have been out of place within the context of the Droids cartoon - caused the POTF coin to be deemed inappropriate for the line and subsequently pulled in favor of a new "Droids" sculpt. The fact that the similar change-over that occured in the case of the C3PO coin came later down the road, might be attributed to the original featuring a much more Droids-appropriate motif. Its anyone's guess, really, what the story is here, but it has been suggested that some of these gold versions did, in fact, make it onto Droids cards and into extremely limited distribution. Given the lack of existing Droids Artoos that feature this coin, however, this scenario might be considered an unlikely one.
