The mass of a United States coin composed of 90% silver and minted before 1965, specifically a denomination of twenty-five cents, is a measurable physical property. This property is typically expressed in grams or grains and serves as a key identifier of authenticity and potential precious metal content. For example, a genuine pre-1965 coin of this denomination should possess a mass within a very narrow, established range.
Knowledge of this mass is important for several reasons. It assists in verifying the coin’s legitimacy, differentiating it from base metal counterfeits or later clad issues. Furthermore, it allows for the calculation of the coin’s intrinsic value based on the current spot price of silver, appealing to collectors, investors, and numismatists alike. Historically, this denomination played a significant role in daily commerce, making its physical attributes widely recognized.
