Now and then. Found two Rosies in the coin star in the last month. Last year, I was behind a women in the liquor store, she dropped a dime. I bent over to pick it up for her and was shocked to see it was a Barber dime. I explained that it could be worth something, she said you can have it. She then looked in her change purse and exclaimed, "here's another one" and handed it to me. Sure enough, another Barber, I again explained what they were and she just said, "I have no interest in them" keep them.
Last week in change I got a wheat and a war nickel in change. Needless to say, I always check.
