I was in Turkey in 1990 when the world cup was on, Italia 90, and i was getting 14,000 Lira to the pound. A few years after the country economy went in to freefall. They removed six zeros from the currency so 1 million old Lira was only worth 1 new Lira i would think that hit a few people very hard.
Dave, your £48 devalue in 3 years sounds not bad compared.
