I found this in my backyard. It looks like aluminum but seems to be to heavy. Lead? It has what looks like 2 1/2 on it and the word warrantied. It rang in about 88 on the AT pro.
Interesting, I have never had anything lead, and large, ring up over 70 on the ATPro. It must be some kind of alloy or it has silver in it. A metal test kit may give you your answer. Sub
