KM-370.11 ½r 1835/4 Z OM (Stack’s Bowers Kirk Menczer Collection, 23 June 2026, lot 72249) 

One real

Diameter 20 mm. 3.380 g, 0.90277 silver

KM-372.10 1r 1833 Zs OM –apparent retrograde “E” in MEXICANA

Repunched letters in the legend are common in Republic coinage. Poor quality, poor training or simply a lack of attention to detail by the mint are possible culprits in how these could have occurred. In this example, the “E” in MEXICANA appears to have been punched in retrograde and then punched correctly to eventually appear like a square “ ”.
