Cissy18 Valued Member United States 51 Posts	Posted 06/11/2025 01:49 am Bought this as a bronze ancient greek coin but it's pretty heavy (2.97g) and gold colored with some tarnishing. Could this be electrum? Report this Post to the Staff

Second, that surface pitting suggest to me that the metal might be copper-based rather than a gold/silver alloy. However, knowing the specific density would be a great way to confirm. Any chance of you performing this non-destructive test and then posting the results to this thread? Thx.

Cissy18 Valued Member United States 51 Posts	Posted 06/11/2025 07:43 am Thanks for the reply! Sure I can try the test. How do I do it? Report this Post to the Staff
Cissy18 Valued Member United States 51 Posts	Posted 06/11/2025 08:00 am Ok I think the density is 7.81. Divided the weight of the coin (2.97g) by the weight suspended in water (0.38). Hope I did that right! Report this Post to the Staff

Sap Moderator Australia 16810 Posts	Posted 06/11/2025 8:32 pm 7.81 is way too low to be anything containing a significant amount of either gold or silver. It's a typical density for brass, or perhaps even iron. The pitting and corrosion are also evidence that it is not actually made of gold or silver. I'm not seeing much actual design stamped on this item. It might be an ancient weight, rather than a coin. 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
