Sorry but I just can't decipher these things so perhaps an expert can help.
The top one is small 12mm, extremely thin, and weighs 0.35 grams. The lower one is I think a dump of some grade of silver. It measures 14mm, is about 2.6mm thick, and weighs 3.38 grams.
Perhaps some one who knows these things can help. After I look at a few of these in SCWC, they all look alike to my 80 year old eyes. Thanks in advance
