First, welcome to the neighborhood, Joe! What is it worth? How much did it cost you in the time it took to dig the hole? ~ Chris
Very cool! She appears to be in good shape having been in the ground 75 years. Usually dimes from that time period are very worn..... That is a common year and having been in the ground and subsequently cleaned up, the old dime will be rendered as damaged and not worth a lot. It will be worth a lot more to you as a cool story/conversation piece. edit.... If you have any buddies that have a metal detector, you may have a prime property for doing some more treasure hunting.
A couple of dollars. I personally wouldn’t sell it. Keep it, you have a nice story about how you got it
It's only worth about $1.50 or slightly higher due to the silver content. You should keep it. Welcome to CT.
