SO here is this interesting piece I recently acquired. I cant rightly say what it is. The coin I have is Copper double struck 1928 Hindenburg Medal. These medals were struck in brass (See the example pictures) and the die patterns are identical to my example. So i guess the question is is it a test strike or just a mistake? Hopefully some one might have some idea or past experience for something like this.
@Old World Coins It looks to me like it was an intentional double-strike on a copper planchet. CONECA created a double-strike for their 25th Anniversary. Sorry! I don't have the photo of the reverse.
