Sap Moderator Australia 17000 Posts	Posted 03/30/2014 12:43 am China never made a "5 yuan piece", even though it says "5 yuan" in Chinese on the reverse. Nobody in the 20th century made circulating silver coins this big. It is entirely non-genuine. I also highly doubt it is silver, whatever the spec.gravity says. Vary rarely are these "fantasy coins" made of genuine silver. 27 grams is the correct weight for a 1 yuan, but the 1 yuan coin is not that large. It is either considerably thinner than a typical crown-sized coin, or considerably less dense. If the latter, then the specific gravity should be way out. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff

Sap Moderator Australia 17000 Posts	Posted 03/30/2014 09:37 am Quote: sap weight is 27grams weight in water is 2.49 grams specific gravity is 10.8 does tat sound right I assume you meant to say "24.49". A weight in water of only 2.49 means it's almost floating so would give an SG pretty close to 1. SG = 27 / (27 - 24.49) = 10.8 Quote: here is a coin 45.5mm like mine must be fake also from the Gansu province (Kansu)) The Krause listing for KM/Y 407 shows a perfectly normal-sized dollar coin, 38mm across. If the numista one really were 45mm rather than a typo, then yes, it's fake. The picture was pulled from a Heritage auction so I'm pretty sure it's genuine; I'd assume Numista simply has the size wrong. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
