Republic gold 10 Pesos 1882 Do-C AU58 NGC, Durango mint, KM413.3. A very rare mint, date, and assayer combination for the series, especially so when found in a grade such as this--a mere 4 examples achieving Mint State certification by NGC. Though the mintage for this particular piece does not appear to be recorded, it seems safe to assume that it is among the smaller numbers for the Durango mint.
