hello everyone this is my first post here .I've been following this forum since i bought my v3 about 1 year now .i can't tell you how much all of you have helped me with the v . THANKYOU ALL i've found some real neat stuff . this spring my first half dime Canadian ,first barber dime ,. last Saturday i found my most valuable coin a 1875 cc twenty cent i had been over that area several times . with some recent rains i decided to do a real systematic search of smaller areas with the super 12 . the coin hit at a solid 84 showing 8" depth. thats where it was i couldn't believe it was a seated quarter there after the times i had been over it . when i got home and was rinsing it off i discovered it was a twenty.thanks bill
