I have a tale from when I was a kid working the register at a burger place back in about 1975. I opened a roll of dimes, and every single one of them were from the 1910's to the '1940's. Opened another one. The same., Another the same. Ended up buying all the dimes, and 90% of them were Mercury dimes, many in near uncirculated condition. (4 rolls) for $20. Not a bad investment for a 18 year old kid back in the day.
Way back when the Hunts were trying to buy all the silver in the world I had a couple of rolls of silver dimes and I needed another motorcycle. I took the dimes to the local coin shop and they were offering 8 for 1. I knew that there were better deals than that out there and found 18 for 1 at a hock shop and traded. The next day silver plateaued and the offered ratios dropped pretty hard at the pawn shops. I bought my motorcycle with enough left over to change the oil and fill the tank.
