The prices come from the feed, and the feed has not answered yet.
Philharmonic 1/10 oz — A tenth of an ounce with a ten-euro face value: Europe’s small gold coin, pure, 16 mm across, and legal tender in Austria whatever it is worth as metal.
Britannia 1/10 oz — A tenth of an ounce of pure gold at 16.5 mm, ten pounds on its face. The smallest coin in the family, and the one the Mint sells most of to first-time buyers.
Both are struck in 999.9 ‰ · 24 kt: the same alloy, the same feel in the hand, and any difference on the scale is a difference in gold.
Both are modern bullion coins, struck for investors — Philharmonic 1/10 oz since 1991, Britannia 1/10 oz since 1987 — and priced on their metal and the margins above it.
So the comparison is the premium. Whichever of the two a dealer asks less for above its metal is the cheaper gold that day — and that changes shop by shop and day by day, which is what the numbers above are for.
