Sword Posted April 14, 2023 Posted April 14, 2023 The designs of the coronation coins: https://www.royalmint.com/shop/monarch/charles-iii/coronation/ A crowned portrait of the king is unexpected but rather nice. I like the reverse designs too (except for that of the crown which looks poor). All in all, a good effort from the RM I think. 2 Quote

Presumably, the redness of the gold is determined by the percentage of copper alloyed. Any added silver would make the coin more yellow. https://www.chards.co.uk/guides/analysis-of-alloy-content-of-gold-sovereigns/180 Quote

Sword Posted April 16, 2023 Author Posted April 16, 2023 I think the 100 pound is made of 99.99% gold and the sovereign is the usual 91.7% gold alloyed with copper. Quote
