You should not guess or assume anything. Its best to just stick to the facts or risk a big loss or if nothing else big headache.
From my statement I would be err'ing on the side of caution by not thinking they are real unless a specific gravity was done. So I'd think I'd be safe in that regard.
Well I can not argue with that good sir. However I would still be interested in if the simple tissue test holds merit. But come to think of it I never even use the tissue test anyways lol...
^ If it is plated decently that test will be of no use. Counterfieters have cranked out other fake silver coins (pandas') that pass gravity test (with correct composition of Lead and Tin). Of course a magnetic slide test could work to identify those fakes'.
Wow this sux.I dont worry too much about fakes because most of my purchases are graded coins from TPGs with guarentees and I buy from big name internet dealers for my 1 oz coins.I look at e bay deals but most are above the dealers prices, and of course if a deal seems too good to be true,it usually is so I pass.If I pay a premium by getting the coins or bars from dealers,thats ok because I sleep very soundly at night.
Tungsten has pretty much the same density as gold, so gold plated tungsten would pass a density test. Check out the link http://www.tungsten-alloy.com/en/alloy11.htm
