Albert Pillar of the Community United States 1915 Posts	Posted 06/09/2019 10:01 pm I enjoy collecting deceptive coinage and this is the first cob in the collection. Specific Gravity is 8.3 compared to about 10.3 if it was genuine. Parts of the obverse appear to be "peeling off". The edge and reverse have "holes & pits". Weight is way off at 17.7 grams and compares favorably to a bronze alloy. Edited by Albert 06/09/2019 10:04 pm Report this Post to the Staff

sel_69l Bedrock of the Community Australia 21788 Posts	Posted 06/10/2019 02:19 am Pure copper 8.93 g/c, pure silver 10.5 g/cc. It looks to be 'coppery'. Rub it with your fingers. Skin oils are slightly acidic and have sulphur as well. OK to do this, if it is a known fake. The oils will react with the metal, and will give a distinctive 'copper' smell. Not a greatly useful test, because high silver alloy (~80%) can smell similar. Edited by sel_69l 06/10/2019 05:46 am Report this Post to the Staff

Albert Pillar of the Community United States 1915 Posts	Posted 07/10/2019 6:34 pm Yes I do mean to include counterfeit and fake coinage as "deceptive". I have collected and documented many. Many Chinese that have never been represented here. A superb field of study, discovery, seek and included in the hobby. "Clandestine Coinage" can be a part of the study. "Claimed Fakes" that proved to be genuine are a part. "Claimed Genuine" coins that I bought and later proved to be fakes are also a part of the study. Report this Post to the Staff
