I collected as a kid. Always used to get uncirculated sets and proof sets for Christmas. I also used to order the U.S. Mint commemorative coins, but haven't for a while. I don't even know what many of them are worth today. A few I ordered had low mintages.
I once rented a metal detector and within 15 minutes of using it found an 1867 Shield Nicked at an old abandoned farmstead.
