Went back to the fairgrounds this afternoon for a 2 hour hunt.. ended up with 5.33 in clad, 1943 Silver quarter, a Silver ring, NYC Police badge (a least part of one), and some kind of relic.. I have no idea what it is.
Just need 3 more silver coins to make my 50 goal.. its a shame that I don't know anyone who finds 400 silver coins a year to make a donation to my goal lol
