Standardized Short-Wave Infrared Hyperspectral Imaging for Non-Destructive Spectral Comparison of Coin Denominations, Design Variants, and Surface-Use Conditions

Coins contain multiple types of information, including denomination, design variant, year of issue, and surface condition. This study established a standardized 900–1700 nm short-wave infrared hyperspectral imaging (SWIR-HSI) workflow for controlled and non-destructive spectral c...
