Saturday 4-11 I decided to try a 1950's era school in the hopes I could score one deep overlooked silver coin. The three hits that I'd call deep and sweet produced two pieces of sterling and a clad quarter. I was using my V3i with 12 x 10 SEF. I recall that sterling spoon is bent up like a cooker - jr. High school drug education class. I don't want to think it was used for that and besides .925?
On Tuesday my stepson had permission to hunt a friends yard, house built 1952. I don't get too excited about homes from that era. The potential for silver is there and it was built on former farmland like much of the town. the four wheat backs were a single spill with two stuck together at about 6. The 1943 dime was less than a foot off to the side. The musket ball was actually pulled on 4-15 from a colonial site. I used the AT Pro for the house yard and it is a great coin hound.
Yesterday I got huge surprise trying the AT Pro at a small site I take every coin hunting unit I've had over the last 25+ years. The soil is is red with iron minerals and the ground balance came in at 92 on the ATP. I ran stable at full sens with the pro audio custom mode. Little signal, but clean showing 81 - 85 at an indicated 8. When I located the edge of the target I thought it was a heavily worn standing liberty quarter from my best hunch. Instead it was way better because the date is the last thing to wear completely on a seated quarter! She's a real smoothie, maybe 50+ years of circulation.
