This coin is a 2017 San Francisco Minted quarter from the America the Beautiful Quarters series, specifically produced in a Proof finish. As a quarter with a denomination of 25 cents, it weighs 5.67 grams and has a diameter of 24.3 millimeters. The coin is crafted from copper-nickel clad copper, showcasing the quality and detail characteristic of Proof coins. The America the Beautiful Quarters series celebrates the diverse national parks and sites across the United States, although the specific design for this quarter would need to be identified based on the particular state or site it represents. Since it was minted in San Francisco, it carries the 'S' mint mark, signifying its origin. While the precise mintage figure is noted as '0', this could indicate that specific data is unavailable or yet to be published, which is common during the early stages of coin production documentation. Collectors often value Proof coins for their pristine condition and limited production runs, making this piece an appealing addition for numismatists focused on American coins.
