The weight is 129 grms.I brought to a pawn shop to do a test and it tested for 18k but when he went to wipe away the mark it stayed on the streak plate so he said it was not real
Then why do you think it's gold, looks like lead, was first thing that pop in my head when I opened the pic. I know with myself when I find things they always start out being gold or silver even when I know better. Iv'e done that to myself a hundred times. I would think the pawn store would know what gold is, they deal with it every day. Don't take me wrong, i'm just trying to help you ID it. I'm not belittling your find, looks like it got heated up in a fire and blobbed up like that, I find allot of aluminum like that.
