Hinkle Posted March 27 Share Posted March 27 I don't come across these very often in circulation. Pulled this out of a bank roll, and noticed the mint mark. I'm thinking die chip just because I'm not seeing no where else on the mint mark of shifting. Any thoughts what might be happening here.

Greenstang Posted March 27 Share Posted March 27 Looks like a small die chip on the top of the S. EagleRJO 1 Link to comment Share on other sites More sharing options...

EagleRJO Posted March 27 Share Posted March 27 I think that by 1965 the US mint was punching mint marks onto working hubs, not working dies, so it doesn't seem likely your 1985 cent would have a re-punched mark. Hinkle 1 Link to comment Share on other sites More sharing options...
powermad5000 Posted March 28 Share Posted March 28 (edited) A 1985 S Lincoln Memorial cent proof is copper plated with a zinc core. On the business strikes of the Lincolns in the 1980's-early 1990's there were a lot of issues with the plating shifting, bubbling, or cracking. I would imagine even with the extra care to make proofs that there could still be issues with the plating. I am leaning less towards a die chip as the dies used to make proofs are highly polished and clean and I am leaning more towards an issue with the plating bubbling up in the area of the mintmark.
