I found these little things around a couple of old houses where I live. At one house, they seem to be everywhere. At the other house, they weren't as prevalent but present nonetheless. They "ring" high on my Garrett Ace 400 similar to how a penny would (if anyone reading this is familiar with the Ace 400, they read around 81-82, with an occasional dip to 79). I think they may have been used in the construction of the houses but I don't know what they would be for. I have found more of the ones with square backing than the other ones. Anyone have any ideas? Thanks in advance.
