W.S. Jones Catalogue republished what might be the absolute lowest published retail Platinum price in the second half of the 19th Century: £ 1.20 per Troy Ounce. (That was likely a scrap price, merchants' discount or erroneous data: avoirdupois weight?) It is unknown how dated this price was, but it's highly inconsistent with other catalogues.
This would otherwise indicate a retail Platinum Low circa 1855. US and French catalogues do not indicate any price collapse, but another British catalogue (Ash & Sons) sold Platinum nearly that cheap; that may have been a Silver-Platinum Alloy.

1855/6: Historical perspective.
Identical Theme but regrettably muddled by conversions. Although the source is a British company referring to it's very own catalogue (hence, the English Apothecary or Troy Ounce) the forex was 1907 and not 1855!

Robert Mushet's entry in The Encyclopedia Britannica dates between 1852-60, with a likely price c. 1855/6. It was re-published in 1873. The "current value" (£ 0.4417) appears to be for 3-Credit Roubles (£ 0.4523), rather than 3-Roubles in Silver coin (£ 0.4755) at full-coin. The Platinum Coin is apparently factored 0.9755 Fine, without valuing the other metals, and otherwise "1d" light.
1855: 1 Troy Oz. Platinum (Coin, Scrap) = £ 0.9241 (USD$ 4.52)
