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.

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
