Groningen Copper Stiver

The most intriguing fact about the Groningen Copper Stiver is that it was minted in a province freshly independent from Spanish rule, often featuring the rampant lion of Groningen on its obverse to symbolize local defiance.

This copper coin, produced from 1594 through 1795, circulated as everyday currency in the northern Netherlands, handling transactions from market stalls to tavern tabs. Struck at the provincial mint in Groningen, it came in various weights, sometimes as light as a few grams, reflecting the era's makeshift metallurgy. We don't know exact mintage figures; records from that period are scarce, likely destroyed in later conflicts.

Design-wise, the reverse typically showed the year and denomination, but quality varied—some strikes were crisp, others blurred from worn dies. If you're handling one, note the patina; it's often a deep green, courtesy of centuries in damp soil.

As for myths, I've heard tales of hidden treasures in old canals, but that's just romantic nonsense. Most ended up as pocket change, not pirate loot.
