Philharmonic 1 oz — Europe’s own one-ounce coin, and the only one with a euro face value. Wide and thin: 37 mm across for the same ounce of gold.
Britannia 1 oz — Struck in 999.9 gold since 2013 — earlier ones are 22 carat. Legal tender in the United Kingdom, which is what exempts it from capital gains tax there.
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 oz since 1989, Britannia 1 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.
