UK, 1838: Griffin's ; Palladium's Price by Bulk, in relation to Platinum & Gold

The All-Platinum Spoon is presumably larger &heavier than the 1825 version; it is 4-5 x more costly.  (The original type spoon, without a silver handle, is indicated below as a "small cup" and sold at the same rate minus the silver handle.)










By 1838, the price of Palladium was expressed as a specific and stable bulk value ratio to both Gold and Platinum.  (This particular ratio is repeated erroneously for years thereafter, because Palladium's price did fluctuate dramatically.)   

This may mark a Palladium Price Low, the first and only time Palladium was cheaper than Platinum in the stable period of the 19th Century.  

By late 20th Century measurement (purest metal), 1 cubic inch (16 cm3) of Platinum weighs 11.28 troy oz (0.34 kg) and 1 cubic inch of Palladium weighs 6.9 oz avoirdupois (12.02 g/cnv')

By weight, where Fine Gold was £4.2477/oz. (and a specific gravity of 19.257) and since Palladium calculates at 51.5% the bulk-weight of Platinum (20.980):

1 cu. in. Au = £43.1569; 1 cu. in. Pd ~ £ 5.2436; 1 cu. in. Pt ~ £ 11.6534;


c.1838: 1 Troy Ounce Palladium (wholesale)  ~ £ 0.8748 (USD$ 4.37)

c.1838: 1 Troy Ounce Platinum (wholesale)  ~ £ 1.0870 (USD$ 5.44)

1835: 1 Troy Ounce Palladium (refined, whols.)  = £ 2.20 (USD$ 10.67)
1835: 1 Troy Ounce Platinum (manufactured, whols.)  = £ 1.70 (USD$ 8.25)

1845: 1 Troy Ounce Platinum (semi-mfg whols.)  = £ 1.00

c. 1827

1893:


The price of Palladium was considered "very high" in France just a few years later, suggesting a shortage there. (Or a price-hike w/ new demand or speculation?) Extreme volatility was witnessed a decade later, c. 1856-65.

1844:

Later encyclopedias and 'fact books' repeat scarcity & high prices, more than a decade after 1832.

c.1837


Where the French pied cube is 1.209367 Cubic Feet (2,089.78 cu. in.,English), and where 1,092+ "livres" is 17,202 Troy Ounces, a French scientist noted (c.1800) :

1 cubic inch of platina = 8.22 troy ounces
1 cubic inch of refined Platinum (refined) = 10.278 troy ounces
1 cubic inch of Platinum (refined, forged) = 10.719 troy ounces 

By the mid-19th Century, cited weights implied greater purity:

1 cubic inch of platina = 10.29 troy ounces
1 cubic inch of Platinum (cast) = 10.72 troy ounces
1 cubic inch of Platinum (rolled) = 11.3252 - 11.64 troy oz.

1 cubic inch of Platinum (.9999 Fine) = 11.30 troy oz.
1 cubic inch of Palladium (.9999 Fine) = 6.322 troy oz.
1 cubic inch of Iridium (.9999 Fine) = 11.849 troy oz.
1 cubic inch of Osmium (.9999 Fine) = 11.854 troy oz.
1 cubic inch of Rhodium (.9999 Fine) = 12.44 troy oz.
1 cubic inch of Ruthenium (.9999 Fine) = 12.20 troy oz.

1838 Victoria, 24k Gold, Eimer 1315, 36.5 mm, ~31.5 g
1838 Victoria, Silver, Eimer 1315, 37 mm, 21.7 g

October 1905:

Where Pistrucci's 1838 Coronation Medal in Gold was valued at £ 4.99/Ozt when London Spot Gold was £ 4.244, the numismatic premium on an 1838 Pistrucci Medal was 17.52%.

It appears the same premium on an 1838 Pistrucci Platinum Medal was ~38.8%.

October 1905: 1 Troy Oz. Platinum (UK: Mkt)  ~ £ 7.983
October 1905: 1 Troy Oz. Platinum (Medal, Numismatic)  ~ £ 11.

October 1905: Est. 33.9 g Platinum Medal (Numismatic) = £ 12.
