So I've had just incredible luck on eBay wheats recently. Out of about 500 cents total, bought for less than $0.04 each, I've found: 1927-D/D RPM001 1913-S F15 1915-S F15++ 1916-D F15++ 1921-S VF20 and not even halfway through yet! But I son't know much about the 1922-Ds. I found this one and it looks to have a weak MM though I don't know if it qualifies as a 1922 "Weak D" or not. I have heard that almost all the 1922 strikes were weak and I've seen G or VG detail examples graded at VF30 or XF40. So I defer to the experts...
Weak "D"'s are coins where you pretty much have to look to see a "D". The better ones, you would have to use magnification and tip it to the right angle. As for a grade, you don't even have a picture of the whole coin. However, from what I can make out, that might even make XF it just looking at the wear, but there are too many nicks. I would say that it is a 30 or 35.
Sorry about the images. I have a Kodak C763 (cheap point and shoot camera) and it's nearly impossible to get good pictures. I've been sitting down for the past 30 minutes taking dozens of shots with all different sorts of lighting and these are the best details I can get. They don't show most of the detail. For instance there are no bald spots on the wheat heads at all and Lincoln has a good bit of XF detail. Here they are. Does that help? Sorry again for quality, I guess I should invest in some sort of a macro camera for my collection anyway... EDIT: these pictures actually made it look much worse. But at least they give you an idea of the overall appearance, and the "microscope" ones can give an idea of detail...
Putting the marks from teh small pix onto your full size pix and I will stand by what I said - VF 30/35
Thanks for the responses, folks! So is it true then that because of the weak dies on 1922 strikes that you are all grading 10 pts or so higher or have I been undergrading all my wheaties??
