My friend likes to collect president coins, actually, this hobby sounds strange for me. I have a collection hobby too, but my collectibles are quite easy to be found, as i like to collect different size and outlook of Coca Cola from different countries. I have been collecting the cans and bottles of Coca Cola for more 15 years, so i needed an empty room for keeping them. In fact, quite space consuming, just unlike my friend who likes to have coins collection. Coin collection doesn't need much space, and coins will have value too. Maybe i should think of collecting coins, who knows one day i will become a rich lady by collecting them.
