Collectible coins include various types and designs that are often sought after by numismatists. The United States 25-cent coin, known as the quarter, has featured many designs over the years. The 1991 San Francisco quarter is part of the regular production run, which also includes commemorative editions. Quarters produced at the San Francisco Mint often have a "S" mint mark and are collected for their potential rarity and condition, particularly if they were struck in special finishes. Rolls containing these coins can be of interest to collectors seeking to acquire multiple uncirculated examples.
