Graded by PCGS as a MS-62 D over S 2nd Strike and 75% off center. It’s a 1973-D over S and in hand it shows nicely. Just difficult to capture on my cell phone. A nice error and it all shows on the coin. A true mint error. The next to last photo is the best I can get of the over mark.
The D/S designation does not mean D Over S, it means Double Strike. Just for the record the OC means Off Center.
First: It is a 1972 second: not a D over S. D/S means double strike If a D over S it would be in the first line [title] of the insert
