Good morning everyone. I found a doubled 58 and even with my the microscope i still question the possibility. Found one it of 6 58d and both 2 check out on variety vista to me
The 58 P is easy to spot and you will know if you have one.
The 58 D's are very minor doubled dies that may be hard to spot on circulated coins and would command little or no premium.
"Is it possible for it to be a different stage or type?"
A different stage of DDO-001 would still show the dramatic doubling but may have other minor features that changed over the life of the die.
The DDO-002 is unassigned indicating one has not been found or the one found may not have been photographed, it may also be a placeholder that the web developer made for future finds.
