Chihuahua. Revolutionary copper 50 Centavos 1913, KM609a, AU58 BN NGC. An outstanding example of this Revolutionary Hidalgo de Parral 50 Centavos. Right on the cusp of Uncirculated with no noticeable flaws. Somewhat crude, as expected, yet one of the finest known for this type. The silver striking is often encountered, but the copper coin is truly rare.
Estimate: 800-1000 USD
