This paper describes the process of design and implementation of searchable digital image library of commemorative and circular coins. The authors discuss some basic problems related with coin recognition process based on color, texture, scale, rotation, contour and shape descriptors. The article describes how to build digital coin library based on coin images and text descriptors. The article places emphasis on process of preparation of indexed pre-calculated templates, which can be used for search based on averse and reverse coin images. The issues of image quality and information relevancy for specific coin, based on individual relevancy mask are also discussed. The article contains information about both well known and specialized newly designed algorithms and descriptors used for preparation, indexing and recognition processes. Finally, we showed our results, time efficiency of the used algorithms, as well as comparison with existing techniques and future envisioning. Next steps for the final noncommercial concept of searchable Commemorative Coins Image Library are introduced.
