    Description

    Brazil. Jose I 6400 Reis 1770-R. Rio Mint (forgery). KM172.2. Choice XF. A lightweight cast forgery, apparently produced at its present weight of 8 dwt, 1 grain (169.3 grains) and not clipped down to this weight. The edge shows a low relief leafed edge from 3:00 to 8:00 and a slightly different edge device around the rest of the circumference. The coin from which this coin would have been duplicated was likely clipped and partially re-edged, producing this bizarre combination. Interestingly, that coin appears to have been a struck fake: the D of DG is upside down and the die work is somewhat rude. Light yellow surfaces are slightly granular in character, X-scratch behind lowest curls is undoubtedly an early test of authenticity, a few unimportant raised specks on obverse are as unproblematic as they are readily removable.

    The coin from which this cast forgery was made was apparently marked by IH, in other words, this cast counterfeit was produced with the marking already intact. The inside of the IH mark is quite granular internally; this fine detail would have been very difficult to duplicate without these problems via a normal casting process. As such, this is the only cast counterfeit of a regulated coin we have encountered, an important distinction from being a cast counterfeit that was regulated after its mintage. With current collecting interest on circulating counterfeits of this era, this coin should see active bidding. Indeed, we would not be a bit surprised to see its price realize surpass that of the authentic 1771 piece marked by IH.

    Provenance: Acquired from Ralph Gordon via private treaty. Plated in Gordon's West Indies Countermarked Gold Coins, p. 201.
    From the Edward Roehrs Collection of U.S. Regulated Gold.


    Estimate: $10,000 - $20,000.
