I do remember these 500,000 Peso notes from Argentina. They circulated between 1980 and 1983 when the currency was changed to a new one. Towards the end of their life they were worth about US$5. Anyway, it seemed like a nice illustration to point out that our blog has surpassed the 500,000 visitors mark today. On the same year that production of Royal Enfields topped 500,000 as well. Thanks for reading!
