UK, 1877: PGMs in Griffin's Catalogue

1877:
Griffin's 1877 Catalogue shows an older, erroneous Platinum Price. Assuming the same 5s. per Ozt charge on manufacture of simple Platinumware, the correct Platinum Price may be ascertained.

1877: 1 Ozt. Platinum (Semi-Mfg, Error: Old Price!) = £ 1.65 (USD$ 8.51)
1877: 1 Ozt. Platinum (Unmfg) = £ 2.35 (USD$ 12.12)
1877: 1 Ozt. Platinum (Mfg: Spatula) = £ 2.60 (USD$ 13.67)

1877: 1 Ozt. Platinum (UK Mfg, Crucibles) = £ 2.65 (USD$ 13.67)

Labor for UK Platinumware, charged retail in 1877, was probably 5s 6d./Ozt.

Assuming a 5s. 6d. per manufacture charge on basic Platinumware, the correct Platinum Price may be correctly ascertained. Platinumware prices were not updated accurately.
