New picture added---hopefully clear enough. Original posting: I cannot find any reference info. for this 1974 S penny. I believe the mint mark to be doubled and have included 3 angles of the mm, and the negative of each which also show details. At first I thought it was smashed, but after looking at different angles, I believe it is doubled. Please let me know what you think. The pictures should show well when moused over and enlarged. Thank you for looking and I look forward to hearing what you think. **I replaced the first picture in hopes that is clearer.
