I’ve personally found 1 1901 $20. I have a friend that bagged 16 $20’s and a $10 on a grading site. Another guy I know got a spectacular key date $10 worth $30,000-$35,000 a few years back.
I found mine with the ole “Mark I Eyeball”, that irked my detecting buddies to no end...
They’re still out there! They usually end up being where you find them ;-)
Cool! I did some work at a site locating old tanks, debris, etc. out in New York. They dug one of the areas up and figured it was an old outhouse location with all sorts of stuff in it. They pulled up old bottles, coins and buttons from the Revolutionary War era. (I should have asked for a cut!).
