Italy, 1916

From 1912 - 1916, the inflation rate of London 'official Platinum Price' was 52.63%.  The New York Platinum Price rose 97.5%.  Ettore Mollinari (or the translator of the 1919 4th Edition) suggests the actual Italian Platinum Price inflation-rate was 232.4% .

In 1912, the Lire/Sterling exchange was ₤ 23.83 : £ 1. (₤ 1. : £ 0.03871) and January 1917, the Lire/Sterling exchange was ₤ 32.78 : £ 1. (₤ 1. : £ 0.03051), so the Lire inflation rate of London Platinum should have been ~ 93.7%.

1912: 1 Troy Ounce Platinum (@ London, refined ingot?) = £ 9.50 (₤ 245.4)  
1916: 1 Troy Ounce Platinum (@ London, refined ingot?) = £ 14.50 (₤ 475.3)

1916: 1 Troy Ounce Platinum (Genoa Price) ~ £ 24.88 (₤ 816.)
