I got this Mercury Dime and it had a couple of claims and I just don't know what to make of them. This is a 1941 Silver Dime and it is said to have a double rim on one side of the coin, also I read somewhere that if the "S" mark has the shape of a trumpet at the end, it may be worth more? It looks like a trumpet to me, but again, I'm not sure and last it is said that this coin has a full or partial split bands. I'm attaching 3 pics of close ups of the coin, take a look for yourselves and see if you can help me with this coin. Thank you in advance.
