Perhaps a helpful addition: I collected my change money over several years (about 9kg in total, mostly lower valued coins, since the higher values can be spent easily).
After exchanging them on a bank into useful money: the average Euro coin weights about 3.6 grams and has an average value of 7 cents. :-)
