got premission to hunt a 1940's house turned out the yard had been redone, but found the 43(p) war nickel tucked in by the sidewalk, went out back by the garage and found a 1935(first year issue) washington state tax token on 10 cents or less , other than that only 7 pennies, went to a park and found the 44 Quarter sandwiched with a clad quarter and I will tell you the AT pro is good my readings were 88-89 then it jumped to 92 and it wasnt lying freaked me out and I was happy since it was my First silver Quarter not a SLQ or anything but I will take it Happy hunting to all
