1987 rpm#3. found this rpm list that says these also have some date doubling. this pic was not easy for me to take. http://koinpro.tripod.com/ErrorVarietyList.htm
I would be very suspicious of ANY coin which had an RPM and a Doubled Date and would probably lean more toward machine doubling on one or the other.
the date doubling is from die deterioration according to the list. i just wish i would have bought an slr camera instead of a point and shoot.
they are all still in the us mint sets sealed up. i dont suspect any forgery if that is what you mean by be suspicious. i opened the original mailing packaging my self. i took out one to get a semi decent photo.
some of the guys on LCR just dont like to acknowledge when some of their rare pennies show up. they didnt believe when i showed them the roll of small dates, and they dont believe i found 10 of these rpms.
Thanks for the clarification as on second look, I do see where die deteriortation doubling is present with this RPM. Congrats on finding 10!
