UK, 1907: Numismatic Sale, Pt Roubles

In June 1907 the US market price for regular ingot was USD$ 26.20 ozt. (£ 5.30) ; scrap was $ 20.30 (£ 4.21) Where ingot was 85% pure,

June 1907:  1 Troy Ounce Platinum (US whols. mkt, .999) ~ £ 6.33 

Where the 12-Rouble Coin and 6-Rouble Coin weighed 1.3292 ozt. (638 Grains Troy)  and .6655 ozt, respectively, the August 1907 price for the "fine and scarce date" 6-Rouble Coin sold without numismatic value at the refined market price. 

The numismatic premium for the somewhat rare 1837 12-Rouble Coin at auction was ~ 45%. At that same rate by rarity, in 1907 the 1839 12-Rouble ought to have sold for ~ £ 83., a premium of 1,200%. 

About 100 years later, UBS Gold & Numismatics (Auction 50, Feb 1, 2001) actually sold a 1839 12-Rouble for $60,500 (equivalent to $45,517/ozt.) or a premium of 7,436% over the intrinsic value  (Pt = USD$ 604./ozt.)

1848: 1 Troy Oz. Fine Gold (Coined?) = $ 20.75



Circa 1847-8, California Gold was so plentiful and material so scarce that absurd prices (in gold) for everyday commodities appeared in mining communities of the hinterlands.

These circumstance were almost identical to travelers' reports of ridiculously high prices in Choco, Colombia. In both locales, platina was often thrown away.
