Yes there is, it's DDO-002 (concea) and it shows doubling in the date and "TRUST" I think this sequence also means something, but i don't know FS-50-1962-101
This is the ID from the Cherrypickers Guide....... FS - Fivaz/Stanton 50 - Half dollar 1962 - Year 101 - Item # Chris
Thanks for explaining! Sorry there isn't anything in the cherrypickers guide about the reverse, just wait for the experts to chime in.
This is in a proof set still in the cello. I've had it for a long time but never thought about looking at it under a loupe. Was thinking about breaking up the set and decided to look at it more closely. Should I, or would it be necessary, to break it out and send it in for attribution?
