Catalogo Gigante, developed by Gigante Editore, is the first-ever app dedicated to Italian numismatics. It is an indispensable tool for professionals and collectors alike. The app is the digital version of the renowned Catalogo Gigante, which was first published in 1992 and has become a bestseller in the Italian coin collecting community.

Catalogo Gigante is complete with images of coins and their respective enlargements, detailed descriptions, minting variations, rarity, studies, and valuations of coins in various states of preservation and respective market data. The digital catalog includes coins from the Kingdom of Sardinia, Kingdom of Italy, RSI, Eritrean Colony, Italian Somalia, Kingdom of Albania, Token Coinage of Fairs and Exhibitions, and Red Cross Tokens.

The app is integrated with Numispedia, an encyclopedic publication of Italian numismatics. Catalogo Gigante is the first-ever "Editorial System" of its kind and is made up of three independent products: the paper edition, digital edition via the app, and the corresponding encyclopedic publication on Numispedia. The app is a revolutionary tool that combines traditional and digital publishing to provide the best information on Italian numismatics.
