20 Euros Capricorn

Part of Germany's ongoing zodiac gold series, the Capricorn issue was produced by one of five German federal mints — Berlin, Hamburg, Karlsruhe, Munich, or Stuttgart — each identifiable by its mint mark. Collectors completing the twelve-sign set must source from multiple mint facilities, since no single mint strikes the entire run.

The 3.89g specification places this squarely in the one-eighth ounce category, a format Germany adopted to bring gold coinage within reach of smaller budgets without abandoning .999 fineness.
