1999 Silver Eagle, lol. OK not a Roll find but someone turned it in at the job I had a few years ago. I nearly died when i seen it laying there. Paid a buck for it!
Last year I was fortunate enough to find a doubled die 1917 wheat cent in a bank box, about a nice VF. Subsequently sold it for $700. Haven't come close since.
1982 DDR, my avatar. found in a roll of cents in 2007. Got written up in all the coin mags. Exhibited it at various coin shows winning a 1/10th oz. of gold and 3 oz. of silver as prizes. I have since sold it for $4000.00
