This is my first time posting since the site has been changed so hopefully I do this correctly. I dug this at a location where there used to be a schoolhouse from 1865 to somewhere around the 1940s. Now there is only a partial foundation and several bottle dumps. It seems to have an imprint of a penny and I believe a date of 1945. It is made of thin copper and has 2 tabs as if it was mounted to something. I’ve never seen this before. Any ideas on what it once was?
I don't think it was made by an impression of a cent piece. I think it is part of a pin, either for the 100th anniversary of his birth (1909) or commemorative of his death. It could be based on the cent piece portrait, although other similar portraits were not uncommon.
Here is a sample of an 100th anniversary ribbon or poster - note the similar design to the cent piece.
