Castilian Cuartillo

The Castilian Cuartillo was often cast in bronze using simple sand molds, a technique that prioritized speed over precision and led to coins with uneven edges and variable weights.

This made it a practical fraction of the real, worth about a quarter, though exact equivalents shifted with regional markets. Minters in cities like Toledo produced these during the 16th century, but records of specific outputs are scarce—many were likely lost in later archival fires.

We know the coin's design featured a simple cross or crown on one side, reflecting Castile's royal symbols, but variations abound due to the casting process. No two seem identical, which can frustrate modern cataloguers.

Planchets were sometimes recycled from scrap metal, including worn reales, turning old currency into something smaller. As for myths about hidden treasures, I've seen enough fakes to stay skeptical.
