Today I gave the small park another try. I detected the same general area I had been working during yesterday's hunt, but from a different direction and at a slower pace. Doing this allowed me to pick up three faint deep signals (9 +) from among the shallower trash and ended up with a beautiful 1920 Walking Liberty half, a worn but nice 1907-O Barber quarter, and a 1888 seated dime. The rest of the silver coins were shallower, averaging about 7 inches in depth. Today's total take - eleven silver coins.
The initial tone I received on the 1920 Walker gave no indication as to what it would be. It wasn't until I was about 3/4 of the way down that the probe alerted me to the possibility of it being a half dollar.
The Barber quarter, too, was a very pleasant surprise. The Washington quarter was my first silver of the day.
The rest of the silver. The seated dime was at just about 9 inches, and there was an antique bottle in the hole with it. A photo of the old bottle is below.
One of the mercury dimes as dug.
There were plenty of more wheat cents too.
The old bottle that was in the hole with the seated dime.
HH!
