c.1861: Estimated 'Reasonable Gold Yield' for Atrato was $2,000,000, with $20,000 in platina.
If Negroes had a little more interest, the gold gathered in situ at the basin of the Atrato would not be lower than two million pesos {$ 2,000,000}per year, with about $ 20,000 in platina, which usually is mixed with placer gold; more of what I've already said on this particular.

In Vienna 1822, Platinum retailed for Fl. 860./kg (~Fr. 2,239/kg.) Platinumware was ~10x (9.82 -10.23x) the Price of Silverware, retail. Likewise, retail Platinum was 53% (about half) the Retail Price of Goldwares, where Gold jewelry retailed for ~2.3 - 2.5x the Price of Platinum chains.
Assuming the Wien Loth in Silver at 17.575 g. and where Florin C.M. (11.6861 g. Fine Ag) so Fl. C.M. 1. = Fr. 2.6034 (2 Mo. Bill: Fr. 2.5157); $0.4858
1822: 1 Troy Oz. Platinum (Vienna: Mfg, Retail) = Fl C.M. 26.745 (Fr. 69.63)
Late 1822: 1 Troy Oz. Silver (.812 Fine) = Fl C.M. 2.2122
Late 1822: 1 Troy Oz. Silver (.937 Fine) = Fl C.M. 2.3597
Late 1822: 1 Troy Oz. Silver (.999 Fine) = Fl C.M. 2.7244
Late 1822: 1 Troy Oz. Silver (Bid: .999 Fine) = Fl C.M. 2.6154
Late 1822: 1 Troy Oz. Silverware (.812, Intrinsic) = Fl C.M. 2.6546
Late 1822: 1 Troy Oz. Silver (Vienna: Intrinsic, Coin) = Fl C.M. 2.6616
In Vienna, platinum is made in objects which, if readily available, are cheaper than gold. Thus, for example, watch-chains, pocket-chains, etc. cost per Ducatengewicht {3.489 g} Fl C.M. 3. The Loth of Silverware 13löthigem
in silver content is worth Fl. C.M. 1.25 but scrap paid at Fl. 1.20, because you are billed for the loss in remelting; 15löthiges silver is paid about Fl. .0667 - .0833 C.M. dearer. The best value manufacture is the larger silver spoon, by which cost, together with hallmark and work, Fl. 1.50 per Loth ; the coffee spoon comes abit higher - namely at Fl. 1.60 per Loth; larger items, such as Lavoirs, pots, plates, etc. cost Fl. 1.75 to Fl. 1.80; items with openwork, with visible hinges etc., Fl 2. per Loth.

The prices are extremely different according to fineness, weight and work. In general, they are much lower in recent times, very beautiful wares but now come to stand noticeably high. Without fashioning, which in some wares is .25, .50, .66 more than the raw material, the Ducat-Weight No. 1 comes on Fl. 1.50, No. 2 to Fl. 2.50, No. 3 on Fl. 3.50; in Ducatengold, {Ducat-Weight} stands at Fl. 4.50.
