Collectible coins are numismatic items valued for their rarity, historical significance, or unique features rather than their face value. The 25-cent coin, or quarter, is one of the denominations in the United States currency, and quarters produced at the San Francisco Mint are often sought after by collectors due to their lower mintage and higher quality. The 1985 San Francisco quarters, particularly those marked with the ā€œSā€ mint mark, are part of the proof coin series, offering collectors a polished finish and often packaged in special sets. These coins may be found in rolls or as individual pieces and can vary in value based on condition and demand.
