SamCoin Pillar of the Community United States 3237 Posts	Posted 01/24/2021 12:30 pm As John says, no such thing as an RPM on coins later than 1989. Any doubling on the mint mark of a coin 1990 or later would be a DDO if anything at all. My guess would be MD on this one as John said, but possibly a little DDD as well.

John1 Moderator United States 56855 Posts	Posted 01/24/2021 6:49 pm Not true. On 1990 and newer the MM can be doubled along with the rest of the obverse making it a DDO,but not just the MM. John1 Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 01/24/2021 7:10 pm But this is not a DDO. It is called DDD ( Die Deterioration Doubling) Note the outside field area is affected. This is because die wear flows towards the closest rim direction. If this were a DDO, the the centers of the devices would be enlarged. Not the field outside of the devices area affected. Strong DDD: On a doubled die that is strong that affects the date and mintmark enlarges it on the centers of the devices: DDO affects the centers of the devices. MD affects the outside edges of devices. DDD affects the fields outside of the devices. Report this Post to the Staff
