João V gold 12800 Reis (Dobra) 1731-R AU55 NGC, Rio de Janeiro mint, KM148 (Rare), Prober-295, LMB-226, Bentes-107.01 (R4). Second (Italic) Shield type. An exceptional survivor of a type noted as Rare by the Standard Catalog of World Coins, and distinguished from the relatively more common 1731 Dobra "oval" shield type by its more angular reverse shield. The 1731 Dobra from the Rio mint with the so-called "Italic Shield" is extremely rare, with only a handful of pieces known to exist, most of which are in private museums. As a short-lived type, the 12800 Reis were struck at the Rio de Janeiro mint from 1727 to 1733. Very late in 1731, the Dobra's reverse was redesigned to feature a new polygonal shield to substitute the circular (oval) one, which had been used only on "R" mint coins up to that year. This late-stage change ensured that few examples of this shield type were minted in 1731, making the issue one of the rarest in the Brazilian gold series.
We have only ever encountered a single example of comparable, though lesser, quality: an AU53 NGC-certified example that we offered in September 2009, hammering for $90,000 ($103,500). This brilliant offering reveals a comparable strike, though with bettering centering and plentiful vibrant golden luster preserved throughout glistening fields. The surfaces remain free of all but trivial handling wisps, with the piece's strong preservation acting in concert with its undeniable rarity to culminate in an immensely desirable offering worthy of attention by even the most advanced collectors of Brazilian and Latin American coinage.
