Here is a find by "accident."
In my backyard today, swinging the coil on a fairly warm day in Jersey, and just before sunset, I dug this awesome porcelain dog about 5 inches down!
Why am I getting a signal on something that isn't metal you ask? Well, I must've had a trash target right next to it, and dug this puppy up on accident!
It's marked JAPAN, probably circa 1950s.
