Last week at the grocery one of the workers accosted me in the aisle, asking if I knew anything about pennies. (Apparently they view me as a pretty narrow specialist in half-dollars.) Someone had tried to feed a fairly nice steelie into the self-checkout coin slot, which of course rejected it. Apparently they gave it to the attendant. We have a pretty good class of grocery workers, though -- she opened with "we Googled it, and it looked like it's worth about 50 cents..." So I didn't have to explain that it was neither a counterfeit nor a treasure.
