Interesting fact
The Pattern 20 Pesos - Maximiliano I (Pattern) 1866 from Mexico, made of Copper, is a rare and unique coin that was never circulated. It was created as a pattern coin, meaning it was produced as a prototype or sample for a potential new coin design, but it was ultimately not adopted for use. As a result, only a limited number of these coins were minted, making them highly sought after by collectors.
