Our story

From collectors, for collectors

Numismaniac was founded to share the love and knowledge of coins of its founder, collector Theodoros Patrinos — with those of you taking your first steps in collecting, and with those whose collections call for specialist knowledge and advice to keep growing.

Through our online shop we offer a wide range of modern Greek and world coins, both raw and certified in the highest possible grades, alongside banknotes, medals and the main investment silver coins such as American Eagles, Britannias and Kangaroos.
