ME: I noticed in your change cup on your desk there was a 1942 dime. I collect coins. Would you be willing to sell it?
HER: I’m not going to lie to you, I didn’t even know that coin was in there. You can have it! Is it worth money?
ME: That's funny about the coin. I thought you had set it aside! You don't see Mercury dimes in change too much anymore. It's one of the more common dates of the series, but I would give you $2.00 for it.
HER: Oh my goodness, you don’t need to give me anything for it, I just really appreciate all your help Thank you!
Sweet! I thought for sure she knew what it was and had specially kept it, being it was one silver dime among a bunch of shiny pennies. But it sounds like it just came in change from the cafeteria and was thrown in there randomly. Glad I took the honest route and received a nice token of gratitude. It's also good to have someone know you are a coin collector, even though she probably thinks it's silly. Who knows what will turn up next?
