Mexico City, Mexico, klippe 4 reales, 1733MF. 12.95 grams. Typically choice full shield and crown and cross but also bold full date and MF, attractively toned VF with typical hole (yet in an odd place, bottom left of shield / bottom right of cross), much scarcer than its 8R counterpart (and made in just these two denominations).
Estimate: $600 - 900
