The Sydney F. Martin Collection, Part III featured quite a few notable highlights. Featured here is the 1754-B Brazil 6400 Reis with an Ephraim Brasher countermark. This coin sold for $168,000 when it crossed the auction block on Monday, March 20. Our catalogers mention the neatly applied countermark on the obverse of the coin, noting that this is the identical punch used on the famed Brasher doubloons.
