MEXICO. 8 Reales, 1858-Pi MC. Potosi Mint. PCGS MS-62.
KM-377.12; DP-Pi39. While this is the more available of the two assayers for this date, Resplandores notes, "This date is rare," and does not mention any uncirculated examples known. This one is clearly Mint State, with reflective fields and a full strike, although one must note several nicks and bagmarks.
Estimate: $1500.00- $2000.00
