Any significant deviation from this figure could indicate either a counterfeit or a coin that has been altered in some way.
Knowing this specific mass is essential for coin collectors, precious metal investors, and numismatists. It allows for accurate valuation based on the silver content, helps to authenticate the coin’s origin, and provides a benchmark for comparing specimens.
