10 Dollars - Elizabeth II 50 Zecchini

The "50 Zecchini" denomination references the Venetian zecchino — the gold ducat struck at the Zecca mint from 1284 onward — one of medieval Europe's most trusted trade coins, circulated from the Baltic to the Levant for centuries. This Solomon Islands piece belongs to a wave of numismatic issues exploiting that historical prestige while delivering an almost symbolic gold content: 0.311 g places it at one-hundredth of a troy ounce, a collector token rather than a bullion instrument.
