Errers and Varietys Bedrock of the Community United States 73747 Posts	Posted 03/11/2026 2:51 pm Hard to tell with current photo, but it might have been shrunken by acid. If it is, it's not an error and is only worth face value. https://www.error-ref.com/acid-shrunk-coins/ Errers and Varietys.

Dearborn Moderator United States 94892 Posts	Posted 03/11/2026 4:06 pm Does appear that it was 'reduced' by acid. what does the reverse look like? Collecting since 1972.

JimmyD Bedrock of the Community Canada 21586 Posts	Posted 03/11/2026 4:41 pm Can you post a clearer photo of both sides. I'm thinking an acid coin also due to the thin rims but need clearer photos to confirm. Report this Post to the Staff

DOCC Pillar of the Community United States 1502 Posts	Posted 03/12/2026 06:36 am Possible rolled thin planchet since details look strong I swing a metal detector and have a knack for finding dirty old coins.

Petespockets55 Pillar of the Community United States 5770 Posts	Posted 03/12/2026 07:06 am Thanks for the additional images. They are still somewhat out of focus and small. It appears smaller in diameter than the normal cent. This, along with the other items mentioned, is telling me this is smaller due to a corrosive environment. If the planchet was smaller when struck by the dies, either the strength of the devices would be weaker or it would have contacted the collar die and be normal diameter. Words of encouragement are one of the major food groups. We need to consume them regularly to thrive and grow. Report this Post to the Staff
ijn1944 Bedrock of the Community United States 19120 Posts	Posted 03/12/2026 07:13 am Clearly smaller in diameter and not as thick. Like others, I'm thinking the loss of metal is due to corrosive environment exposure. An interesting curiosity. Report this Post to the Staff
JimmyD Bedrock of the Community Canada 21586 Posts	Posted 03/12/2026 07:54 am Still looks acid etched to me. Acid usually attacks the rims first and the rims on your your cent are almost non existent. In any case it is some sort of damage. Report this Post to the Staff
HondoB Bedrock of the Community United States 24977 Posts	Posted 03/12/2026 08:10 am This coin has the hallmarks of having been attacked by acid. Here's one that I found with a similar weight: Inordinately fascinated by bits of metal with strange markings and figures Report this Post to the Staff
