<p>[QUOTE="Joshua Lemons, post: 25790455, member: 82388"]If they aren't magnetic, I think this "patina" and look was achieved by adding a chemical paste, rubbing it in, then wiping the excess. Possibly a very harsh chemical dip too. I've seen some lower grade world coins in pretty dark condition and it just takes a few seconds too long in a silver dip to strip all luster and the coins come out looking like this. One could add up all the correct weights for each coin and then weigh the entire piece. I think if the weight is within 2 grams or so, it's a safe bet it's ok. I haven't seen these coins faked before, though I'm sure they possibly are. </p><p>I own a couple Puerto Rican counterfeits and they look very convincing until they are weighed and they are severely underweight! In my younger days I bought them in eBay because I didn't know better. Many of the fakes can be detected by a magnet and weight.[/QUOTE]</p><p><br /></p>
