Why is it that gold coins are hard to bend when its supposed to be 99% gold and thus should be soft and bendable?

Gold isn't that soft. It's just that there are other, easy to get substances that are harder.

Gold coins intended for circulation aren't 99% pure; those are alloyed with another metal (usually copper) down to about 90% purity, to make them harder and more durable.

Bullion coins are much softer; they normally compensate for the lack of a hardening alloy by being much thicker than a circulation coin of similar diameter.

Depends on the coin, some are pure (24k, Phils, CML's) some aren't (22k GAE's Krugs)

Thanks but say how about a mesh, possibly of another metal type, inside the gold coin, to make it rigid? Have you heard of such a thing? Another collector told me such but he wasnt sure either
