A live shell?!? Holy....
Well, I dont really think that I will find grenades in the ground here in Michigan, but I saw a few videos on YouTube. I would say this one guy makes about 5 bucks on average a week off of clad coins only. This does not count any valuables (old coins, jewelry, etc). It might be a worthwhile way to make a few extra bucks and work off some weight. My goal would be to try and find a Walking Liberty Half dollar piece in a decent condition somewhere... but i'm not counting on even finding one, let alone it being in good shape.
I have 2 walking liberties, along with some standing liberty quarters, silver Roosevelt dimes, silver Washington quarters, murcury dimes, a barber dime, and some buffalo nickels. Most of these coins are really worn out though, especially the buffalo nickels, some are turning into little disks.
Also have a few Indian head pennies, but they were bought off a collector.
Thanks for the post, would love to hear anyone else's ideas!
