Welcome to CT It maybe very well you have the coin you describe but without pics we wouldn't be able to help you. Imo Dave
Thinness and weight have nothing to do with Doubled Die issues. Do you collect coins? Did you just start? What do you know about Hub Doubling?
I only know a tiny bit more than I know about uploading a photo from the gallery on phone. LOL. I will work on that this morning. I found another coin in the same roll that is similar. The first Roosevelt doesn't look right. I'll be back with photos. No I'm not a collector.
I just noticed the Mint Mark is doubled so it is not Class VI doubled die. Also this doesn't look like Roosevelt to me.
@BeccaBianca It is President Roosevelt What you have is a well circulated Dime The doubling is due to DDD - Die Deterioration Doubling caused by a worn die. Not a Doubled Die
