Sovereign or Philharmonic 1 oz: which is the better buy today?
Sovereign holds 7.32 g of fine gold and Philharmonic 1 oz 31.10 g: Philharmonic 1 oz holds 4.25 times the gold of Sovereign. The metal costs the same per gram in both; what differs is how much of the price is the coin rather than the gold — and the small one always carries more of it.

Sovereign — The small coin of the European market: struck since 1817, sold and bought everywhere, and hard alloy so it survives being handled.
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.
Sovereign is 916.7 ‰ · 22 kt, so it weighs 7.99 g for its 7.32 g of gold; Philharmonic 1 oz is 999.9 ‰ · 24 kt, 31.10 g on the scale. Neither holds more gold for the difference: the alloy is hardness, which is why Sovereign can be handled and Philharmonic 1 oz travels in a capsule.
Both are modern bullion coins, struck for investors — Sovereign since 1817, Philharmonic 1 oz since 1989 — and priced on their metal and the margins above it.
What decides between them is not the gold, which costs the same per gram in both, but everything charged per coin: striking, distribution, the shop’s margin. Spread over 7.32 g the small coin carries far more of it per gram than the big one does over 31.10 g — which is why Sovereign is nearly always the dearer gold, and why it is bought anyway: it sells in smaller pieces, and sells everywhere.
