New (to me) detail on the Mint's alloy for gold coins question

[RDHC]

I have just bought a 2005 quarter ounce gold Britannia. I was a bit worried that it would turn out pinkish like the modern sovereigns, so I was very relieved to read on the BullionbyPost website that for this year the Mint used silver to alloy the Britannias. Just shows that the Mint can do it if it wishes to.

Until 2012 the gold Britannia had  a fineness of 917, starting with 2013 the coins are  9999

As I understand it, the other crucial factor is that the1987-1990 Britannias were alloyed only with copper and have that pinkish tone that I dislike, which still mars the current sovereigns. Those alloyed with silver post-1990 have a pleasant 'old gold' colour. The 0.9999 pure gold coins are impeccably light gold in colour.
