aigroeg New Member United States 1 Posts	Posted 08/10/2017 11:52 am Wondering whether what appears to be a "D" on Lincoln's shirt is a mintmark, and if so, is this unusual? Thanks!! Report this Post to the Staff

Bump111 Pillar of the Community United States 3327 Posts	Posted 08/10/2017 12:14 pm I think what you are seeing is a "D" shaped corrosion spot. These plated zinc coins are notorious for things like that. "Nummi rari mira sunt, si sumptus ferre potes." - Christophorus filius Scotiae Report this Post to the Staff

It's just PMD (Post Minting Damage) - your brain takes random patterns and turns them into recognizable things.

spru Bedrock of the Community United States 12477 Posts	Posted 08/10/2017 12:53 pm It does look like a D mintmark but, unfortunately, it is just damage with zinc rot.

Crazyb0 Rest in Peace 10197 Posts	Posted 08/10/2017 12:56 pm to the family! What you see is the result of the zinc core being exposed to environment (air, moisture). This causes "zinc rot", a corrosive "plating bubble" to form. They pop like zits exposing more of the insides. Usually caused by "split plating" where the thin copper plating gets stretched/torn upon striking or by material on core before plating. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 08/11/2017 2:33 pm No more mint mark punchings after 1989. In 1990 the mint marks were added to the dies design. Just a mark on the coin. PSD If it were a device, then it would be raised if on the fields. No way it could be a device as that area is deep into the die. If it were die damage, then it would be raised. So it is not a mint error. PSD Report this Post to the Staff
