A comprehensive coin dataset highlighting the numismatic heritage of Bangladesh

Following Bangladesh's independence in 1971, the country introduced Taka coins in 1973, featuring a lotus flower and denomination, symbolizing its rich history and cultural heritage. In 2013, a new coin series was issued, displaying the portrait of Bangabandhu Sheikh Mujibur Rahman on the obverse and the national emblem on the reverse. This series included denominations of 1, 2, and 5 Taka coins. In this research, we present a dataset of 9983 images representing 26 different classes of Bangladeshi coins. The dataset includes coins of various denominations, such as 1, 5, 10, 25, and 50 Poisha, as well as 1, 2, and 5 Taka coins. Each image captures the coins from both the obverse and reverse sides, showcasing different shapes, sizes, and designs under diverse environmental conditions and backgrounds. The primary significance of this dataset lies in its ability to assist visually impaired individuals in daily banking transactions. By addressing challenges related to coin detection, recognition, and the integrity of monetary systems, this dataset contributes to the fields of computer vision, artificial intelligence, and machine learning. The technology empowered by this dataset can enable visually impaired individuals to independently and accurately identify and differentiate between various denominations, thus enhancing their participation in the financial sector.
