Perhaps this is a bit off-topic, but about a month ago I was exiting a supermarket and spotted a quarter on the ground, a few feet from the doors. I picked it up, thinking it was simply a common quarter, but just before I put it in my pocket I noticed that the edge was entirely silvery-white. It turned out to be a lightly circulated 1964D quarter. I wonder - was this lost coin accidentally dropped by someone who had been keeping it as a collectible, knowing it was silver, or was it still in circulation and not recognized as special by the one who lost it? Perhaps it had been received in change just a few moments earlier, falling to the ground unnoticed by the shopper. If so, what are the odds of finding a silver quarter on the ground in this day and age? Vanishingly small, indeed. This, despite the fact that hundreds of millions of silver quarters were minted that final year. On rare occasions, I receive silver Roosevelt dimes in change, and I found one in a teller's tray last week at a Bank of America, which I purchased (no- not the bank - just the dime) for ten cents, handing over a nice, new, shiny clad dime in exchange for the worn and dirty silver one.
