While walking home today, along side the train track I saw a dime so I decided to pick it up. Except that part of it is flattened. Upon closer inspection, and comparison with a good dime, it looks as if my dime is now the size of a penny and also has the impression of the back of a penny on the front of the dime and a fainter impression of the front of a penny on the back of the dime. So it's kind of like an 11? coin. Except not.
