Colnect

Founded in 2008 by Amir Wald, Colnect is a global platform that provides extensive, wiki-based catalogs for a wide range of collectibles, including stamps, coins, banknotes, and phone cards. Its mission is to revolutionize the collecting experience by offering tools for collectors to manage their personal collections, identify items, and connect with other collectors to trade or transact. The platform functions as a community-driven resource, with members contributing to and maintaining the accuracy and breadth of the catalogs.
