Yes. Actually "every" hobby can be quite expensive. This maybe "force" you to spend less on other things and try to save some money, and buy some nice medal as a "reward". People appreciate different things. Some go out every day to drink something and complain that they can go only for a short holidays. For some travel is everything and they work hard th whole year to go on some travel, etc. Really interesting collection must be one that spans through different generations. I think smbdy was mentioning in some post in forum that his friend got collection of PM from his father, and his father from his father.
