I am Dema Yurii — a numismatist from Ukraine.
Theme of the collection: coins by name (I try to collect coins of as many names as possible: cent, penny, kopiika, lempira ..).
My numismatic collection (gradually adding my coins to the site: now more than 2000).
I use Wikipedia very often on the topic of my hobby. In general, I believe that this site is one of the five most important Internet resources in the world.
