This application relates to the technical field of coin authentication, and in particular to an automated method and system for coin authenticity authentication based on multispectral image fusion. The method determines the type information of the coin to be authenticated, and moves the coin to be authenticated to either a banknote authentication position or a coin authentication position based on the type information. For the banknote authentication position, multispectral image detection and microscopic feature detection are performed to generate authenticity information. For the banknote authentication position, creases and moisture spots are identified to generate condition information. For the coin authentication position, alloy composition and patina elements are detected to determine authenticity information. For the coin authentication position, data acquisition and model construction of the three-dimensional morphology are performed to obtain condition information.
