Netherlands 25 Cent

The 25-cent guilder coin, minted from 1818 to 2001, holds the record for the longest production run of any Dutch denomination.

That longevity meant it adapted to everything from wars to economic booms, starting in silver and later shifting to cupro-nickel as costs rose. Early versions featured a simple lion rampant, a design that persisted with minor tweaks. Mintage figures vary by year, but records for the 1840s were lost in a mint fire, so we can only guess at the exact numbers.

Over time, it became a staple in pockets across the Netherlands, though variations in edge lettering and weight make some years trickier to identify. If you're handling one from the 1950s, check for the subtle ridge changes; they weren't just for show.

Collectors might quibble over its commonality, but that's the coin's charm—reliable as a rainy Dutch afternoon.
