Portugal
João VI gold 6400 Reis (Peça) 1824 MS63 NGC, Lisbon mint, KM364, Gomes-18.20. Exceptionally eye-appealing with mesmerizing, prooflike gleam in the fields and few noticeable marks over the surfaces. A small flan imperfection behind Joao's head and a touch of incompleteness in the reverse centers prevents a finer grade.
Estimate: 900-1100 USD
