'Pure gold'[edit]

I suggest that the entire "Pure Gold" coin section be deleted. It's got its own section, and is more or less the antonym of this entry. That could lead to confusion, and/or problems where people edit one source of data and not the other. — Preceding unsigned comment added by Riventree (talk • contribs) 12:16, 25 July 2011 (UTC)[reply]

Agree. I've cut this section way down, but left it because it explains why there are now "bullion coins" in crown gold (most bullion coins didn't start out that way). S B H arris 19:05, 25 July 2011 (UTC)[reply]

Need physical properties[edit]
