Piast Silesian Bracteate

The Piast Silesian bracteate was struck on silver sheets so perilously thin—often under 0.5 millimeters—that they sometimes wrinkled under the hammer, imprinting accidental designs.

This made for a coin that was more like a medieval business card, issued by Silesian mints under Piast dukes between 1200 and 1300. They featured simple motifs, such as crude lions or crosses, hammered into one side only, with the reverse left blank or faintly impressed.

We don't know the exact number produced; records from that era are as scarce as honest merchants in a medieval fair. What survives shows variations in style across places like Wrocław or Opole, reflecting local rulers' preferences.

Some specimens bear evidence of multiple strikings, where old coins were reused, turning currency into a palimpsest of history. It's a reminder that not every coin needs two sides to tell a story.
