It used to be common in EU that each country had its own currency. It was interesting to watch the sizes and design of coins. I always hide some change either for its look or I might need it next time when visit ion the country. Sometimes they have nearly no value to change it elsewhere sometimes they are forgotten in my bag and I find them being back home. Sometimes I get them from my friends. They used to put coins on eyes of a dead for he would be able to pay Charon to cross river Styx and to land on the other bank. I have coins for to pay â€œnearlyâ€? all over the world.
