UK, 1871: Louis Casella Catalogue

1871: 1 Troy Oz. Platinum (semi-mfg.& mfg.) ~ £ 1.65 (USD$ 9.0)

1871: 1 Troy Oz. Silver (pure, retail?) ~ £ 0.37 (USD$ 2.05)

Where catalogue prices show stable pricing 1865-71, retail Platinum prices were probably likewise. Casella's Platinum capsules were otherwise known as "covers," priced by size elsewhere, as in Griffin's 1866 Catalogue; see p.186. Comparison illustrates similar prices at these two vendors in different years. (Casella's Grove's Battery was 20% more expensive, however.) Variation in prices among vendors/by location was probably significant, here.

1866: 0.25" = 9 d. ; 1871: 0.25" = 15 d.

1866: 0.38" = 20 d. ; 1871: 0.38" = 21 d.
1866: 0.5" = 2 s. ; 1871: 0.5" = 2 s. 6 d.

1866: 0.75" ~ 3 s. 6 d. ; 1871: 0.75" = 4 s.

1866: 1.0" ~ 5 s. ; 1871: 1.0" = 4 s.

Pure Silver was 49% higher than Spot or Market.

1871: Undetermined Platinum (mfg: Gramme Weight Set), £ 1.50 (USD$ 8.19)

1870-72: According to this estimate, 200 Troy Ounces (£ 300.) might additionally entail recycling cost two-thirds the total Platinum value (4 x £ 50. = £ 200.) with the heaviest usage.

Presumably, the scrap-value was very poor and wholesale prices were charged for 'new' or the Platinum loss was very great.

1872: 1 Troy Oz. Platinum (Mfg., Whols.?) = £ 1.60 ($ 7.80 ; USD$ 8.94)

c.1878?: 1 Troy Oz. Pt (Refined, Bulk: Mkt) = £ 0.82 - 0.96 (USD$ 4.- 4.66)

c. March 1878:

Where 1 Foil 1x4 Sq.In. = £ .045, ~ 11d.


Mid-1878: 1 Ozt. Platinum (Semi-Mfg, Retail) = >£ 1.60 (USD$ 7.73)

December 1878: 1 Ozt. Platinum (semi-mfg, retail) = £ 1.75 (USD$ 8.46)

The total Unit Cost of a single Grove's Cell w/ one 6" x 2" foil (24" sq. surface) is £ 0.23, where a single foil cost £ 0.14 (@ £ 0.01125 per sq.in.) or 59% of the Unit Cost. At a known Platinum price per oz. troy, there might have been 11-12 6"x 2" platinum foils per ounce troy. Presumably, these are 'smaller' foils (by the sheer number used) - or the Platinum price estimation is off by 50%.

At a known Platinum price per oz. troy. There were 6 6"x 3" foils (£ 0.23 each) or 8 platinum foils per ounce troy. Presumably, these are medium-sized foils.

In Grove's Cell, there were four to six (larger) platinum foils per troy ounce by this estimation.

c.1894: 1 Ozt. Platinum (Semi-Mfg, Retail) = £ 2.50 (USD$ 12.20)
