If you found two dimes in 1991 but you didnt have any interest in coins till now...... may be a brother/sister or a cousin took an older date dime and placed the 2006 one instead and because you didnt show interest except these days ..... so you assume that those two are the same that you found.
I think that if you asked around in your family if someone has replaced one of your dimes with another ... you will find your answer
