Old Doubled dies are hard for me to determine because the wear of circulation but what makes me think this coin is one the eyelid according to variety vista the ddo-01 has a doubling on the eyelid which I see in this coin, the date and the legend has some rounding. I dont see anything for comparison
"Medium spread on 19 of date with light spread on eyelid" Here's Variety Vista's photos of 1929s DDO-001. http://www.varietyvista.com/01a LC Doubled Dies Vol 1/1929SDDO001.htm I don't see anything on the date of the OP's coin, could be too worn. The eyelid looks interesting though it could be a conveniently places contact mark. I will try to take photos of a regular eyelid on a 1929 wheat cent to compare with yours.
The eyelid looks different on the plate photo. I think the OP's coin has too much wear for further comparisons. Chris
The doubling on the OP's coin looks more similar to this coin, from another year. http://www.varietyvista.com/01a LC Doubled Dies Vol 1/1930PDDO001.htm
Hmm thats interesting wonder if it would be worth sending to Wexler for him to take a look at it. Just wondering though I have seen other "doubled eye" listed like the 92 that some believe are die gouges. I wonder if this one is a die gouge or a real doubled die. I wouldnt send to have attributed by ANACS because I just dont think that if it is a doubled die it would ever be worth enough for the attribution fee. Still cool looking and a fun find, it has been sitting in my to check pile for a while
I have no opinion on the DD, but I was intrigued by the third image, the very worn, faded one, in which the eye looks very real, in fact quite handsome
A good starting point when/if trying to compare to a known variety is the mintmark (when applicable, of course). While one being in the same position certainly does not prove a coin is indeed of the same variety, being in a different position, even slightly, can tell you that it's not.
