I can confirm that the same happened (and sometimes, nowadays rarely, still happen ) in Italy, the conversion rate from Lira to Euro was 1936.27, so everyone used 2,000 for simplicity, i.e.: "It costs how much? 500 Euro?! That's 1,000,000 Lire!!" the conversion was 2002, so only little more than 20 years ago, people 40 and over have grown up "in local money".
