His eye and the date look doubled to me...and the pics don't capture it the best but it looks like the bottom part of an S is stamped on the D
There were no OMM ( over mint mark) for that year, in fact the last was 1958 if I recall correctly. It is just a D. Sorry, the photos don't show enough details on the eye or date, but they appear normal at this size. Jim
Sorry, but neither this nor the 1969 d are error coins. They’re both just regular circulated cents that show wear. They are not ddos and as stated above, there was no omm for 1969 d.
What you're seeing is the result of an overused die and is fairly common on cents of that general era.
Patience is a virtue, sir. Please do try waiting more than a single minute before becoming impatient because no one has yet answered your question.
