ArticleData in brief2025
A comprehensive coin dataset highlighting the numismatic heritage of Bangladesh.
Article in Data in brief, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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.
