Nic Pillar of the Community Philippines 1156 Posts	Posted 03/31/2010 12:56 am Hi there, just a thing that's been puzzling me and the answer may be out there. I've seen gold coins marked 0.999 pure, well, we know gold is real soft, but when I handle these coins, they are hard, why is that? I have a solid gold ring that's really soft and bendable, and its not even close to a 0.999 purity any ideas why so? thanks! Report this Post to the Staff

Saruma Pillar of the Community United States 968 Posts	Posted 03/31/2010 01:31 am Probably because the coins are thicker and because it is a solid disk not a ring with a hollow center. Imagine stretching and squeezing the coin into the shape of the ring and you will probably see how structure makes a difference. Report this Post to the Staff
