Joao V gold 400 Reis 1725-M, KM118, Russo-230, Gomes-86.01, AU50 NGC. Some light wear apparent, but otherwise a very attractive piece in unusually high grade for this extremely rare type. The damaged RLM collection specimen hammered a few months ago for $9,000. The present piece is from the same pair of dies, characterized by the "G" and "N" in "SIGNO" touching each other. Krause catalog price(s) for this item: $725 in VF, $1200 in EF.
Estimate: 10000-15000 USD
