I have found 245 40% silver halfs since I started this, I think it was in March? Anyways, I have searched 6 boxes and found a total of 14 halfs, the rest were handrolls. I bet I have searched $4000 in handrolls....So you pick which I'd go for.
Also have found 18 90% including 8 Franklins and 2 Walkers. In handrolls or teller trays.
Dimes....I have searched over $2000 in machine rolls and haven't found the first silver. Ususlly avg 1 in $60 in handrolls.
