Be sure to check the value of that Mercury Dime. My coin tale. In 1956 in high school I collected coins. I spent $200 for each denomination and put the best in a blue book. I found a new looking shiny mint 1916 D dime I put in it's slot. Later I sold the blue books I had to a friend for $80 face value. At that time, I never had a book to tell me what they were worth. Now, I think it would grade a MS65 or better. It probably came out of a collection that a child took to spend.
I'm sorry, but your kinda late. Really soon I will put up a contest with a 1950's wheat penny as the prize!
No really, thanks for putting up contests, giving other members, including YN a chance for uncommon or rare coins.
