The invention discloses a paper currency version classification method, an apparatus, equipment and a storage medium thereof. The method comprises the following steps of acquiring a target image corresponding to a target characteristic area of paper money to be identified; detecting whether the target image includes a braille characteristic; if the target image includes the braille characteristic, determining the paper money to be identified to be braille version paper money; and if the target image does not include the braille characteristic, determining the paper money to be identified to be non-braille version paper money. In the prior art, a paper money version is identified by a person so that labor cost is high, efficiency is low and an identification error rate is high. By using the scheme provided in the invention, the above problems are solved. Through the braille characteristic, the version of the paper money to be identified is automatically classified, and detection efficiency and accuracy are increased.
