North Eastern Indian Numismatics
Description
This dataset contains a carefully selected collection of 2147 high-resolution tiff images of ancient and mediaeval coins from the Northeastern regions of India with a total of 51 classes from all four regions. The images of this dataset have been taken from Assam, Tripura, Koch Bihar, and Jaintiapur. This dataset will support research of numismatics, archaeology, cultural heritage digitisation, and image classification with artificial intelligence. The coins have been collected from verified private collections and five reputed auction houses: Marudhar Arts, Oswal Auction, Classical Numismatic Gallery, David Feldman, and Jain Auction House with their permissions. Each coin was examined visually and authenticated using standard numismatic references to confirm its dynasty, denomination, motif type, and inscription style. The coins' inscriptions are written in Assamese, Bengali, Sanskrit, Arabic, and various local scripts. To enable machine learning applications, all images went through standard preprocessing steps, including noise reduction, and resizing to 512 × 512 pixels. The front and back design was kept perfect for each image. The dataset comes with a detailed annotation file that documents metadata, including class labels and numismatic features. It delivers a systematic hierarchical model covering 51 defined coin classes across four regions of the Northeastern Indian dataset.
