I understand if the wheaties get to boring.Trust me it would be nice if we could get down to early large cents.
WOW that's a surprise,have a feeling it's going to be a slow nice.Wish I had one but for now mrgans and peace dollars are within my budget.
At first I thought there may have been a bit of flashing on the edge of the planchet, which then got run through the upsetting mill and pushed up to the edge of the coin. After looking more closely I think these are, as you said, places where the edge of the die got chipped and left tiny cuds along the rim. If the die came down and hit something in the 7:00 area, that conceivably could have caused these tiny chips, as well as the die crack that runs horizontally through the ribbon at the right of the photo. It’s fun to speculate on what might have happened. Edit: Extended the photo to show the entire die crack. Please expand the photo to get full detail.
If they are really cuds / die chips, they should show up on other coins. If they are folded over fins, then this is unique. I need a minion I can send off to scour the web for other photos to see if there are any more of these.
