For the thrill of finding them. My totals are kinda small, can't get rich on my finds yet. They go into the safe deposit box for now, and maybe my grandkids will have fun going thru a nice cache in the years to come.
Now if my son would just find a wife so I could get me some grandkids!
Both! I save my 90%ers for when it's monsoon season pouring down rain, and my 40%ers to buy gold bullion. All others, foreign, wheaties, war nickels, mercs, washers, buttons, tiddly winks, etc. I save cause they're super duper cool.
Saving for now but will sell the 40%s later this year when silver is above $15. I will keep the old stuff for a long time, maybe pass it to niece and nephew.
