The history of KATZ Auction began in 1998 when Stas Katz, being a child, started to collect and trade coins. A life-long hobby turned into the establishing of Katz Coins Notes & Supplies Corp in 2007. We have started with eBay, MA-Shops and numismatic fairs across Europe and came to establish the KATZ Auction at the end of 2015. Since then our Auction is the most important part of our life and our goal is to build the largest online Auction of collectibles in Europe. At our auctions we sell Rare Coins, Paper Money, Medals, Orders, Watches, Weapons, books and all other kinds Of collectables from the Whole World!
