This occurred to me about 5 minutes after submitting today's guess. Matches the year of the prize! Doh.
Me too. I even PM'd the OP and lamented/laughed about wishing I'd said that. If I ever ran a contest similar to this, I'd probably do that Now let's see... although I spent hours counting carefully, marking off each coin as I did, so I think it's not quite right. Unless I counted a LOT of 3 cent pieces as half dimes... lol!
