Sigismund I Half-Dukat

This half-dukat from Sigismund I's reign was struck using gold planchets that likely incorporated alloys from recycled foreign coins, a practical nod to the era's trade networks.

That detail cuts through the usual romanticism; we're talking about a coin that embodied Renaissance Poland's fiscal realities, not some mythical artifact. Issued between 1526 and 1548, it featured the king's monogram or the Polish eagle on one side, with a simple cross on the other—design choices that were straightforward, if unadventurous. Mintage figures remain murky; records from that period were probably lost in later conflicts or fires, so speculation is futile.

I've examined dozens of these over the years, and they hold up well despite their thin strikes, which sometimes led to off-center designs. Not that it matters much—authenticity is what counts, not perfection. As for myths about their supposed rarity, let's just say I've handled more than a few that turned up in old estates, defying the hype.
