So one New Franc was worth £220 and is 'currently' worth 10p? So the best case is the parent already talking about New Francs, in which case my maths was alrea

  I think you're correct that the franc has hugely devalued against the pound in that time. But based on the context from the first paragraph, devchix's post was talking about something different, equating one 1830 franc to £2.2 in today's money, possibly by a "wildly inaccurate" methodology. The historical exchange rate should not be hard to figure out. Both countries were on a gold standard at that time. One 1830 franc was worth 290mg of gold. One 1830 sovereign was worth 7.3g of gold, or about 25 old francs. So using 1 pound = 10 new francs = 1000 old francs, that's about a 40x decline in the franc/pound rate between 1830 and 2000, unless I've made an error somewhere.

    Were talking about large relative declines either way. Considering their fortunes have ebbed and flowed at similar times. Both were super powers of their day, both are now large developed economies, I would have expected the outcomes to be much closer.
