I found this coin in a roll but I never heard of anyone having one can anyone confirm this ? FYI I didn't take any pictures yet.
No pictures... No help No. And we never heard of DDO and DDR at the same time. Probably MD.. Machine Doubling on both sides. This is more likely.
Here's one from 2004: http://lincolncentvarieties.ecrater.com/p/16668812/cherry-pickers-fs-801-2004-lincoln-ddr
Here's a 1941 merc with ddo & ddr: http://www.pcgscoinfacts.com/Coin/Detail/145464 and a 1940-s merc: http://www.pcgscoinfacts.com/Coin/Detail/510030 ...Just because I was digging thru these last night.
If you can call them true doubled die's as John Wexler does with the Shield Cents, there is doubling on the obverse date, coupled with doubling of the designers initials on the reverse on several.
