Marengo 20 Lire holds 5.81 g of fine gold and Panda 30 g 30.00 g: Panda 30 g holds 5.17 times the gold of Marengo 20 Lire. 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.

Marengo 20 Lire — The Italian 20 lire of the Latin Monetary Union — the same 5.81 g of gold as a Napoléon or a Vreneli, which is why the three trade together.
Panda 30 g — Metric rather than imperial — 30 g, not an ounce — and the only one of these whose design changes every year.
Marengo 20 Lire is 900 ‰ · 21.6 kt, so it weighs 6.45 g for its 5.81 g of gold; Panda 30 g is 999 ‰ · 24 kt, 30.00 g on the scale. Neither holds more gold for the difference: the alloy is hardness, which is why Marengo 20 Lire can be handled and Panda 30 g travels in a capsule.
Marengo 20 Lire was money before it was an investment — struck from 1861 to 1897 — and is bought today as a bullion coin on the strength of being recognised everywhere; Panda 30 g has been struck for investors since 2016, and its price is the metal plus the mint’s and the dealer’s margin, nothing else.
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 5.81 g the small coin carries far more of it per gram than the big one does over 30.00 g — which is why Marengo 20 Lire is nearly always the dearer gold, and why it is bought anyway: it sells in smaller pieces, and sells everywhere.
