Mexico
Republic gold 4 Escudos 1857 Mo-GF, Mexico City mint, KM381.6, MS61 NGC. Mint State and thus very scarce or rare (Long reports only one BU coin), showing ample remaining luster albeit surface hairlines account for the grade. Rather well struck since showing more detail than usual in the eagle's breast and thus very attractive.
Estimate: 800-1000 USD
