In the realm of collectible coins, patterns are a specific type of coin produced to test new designs or innovations prior to mass production. The 1885 pattern coins, associated with the United States of America, exemplify this category as they showcase various artistic and technical changes that could potentially be adopted for regular coinage. Often struck in different metals or with unique designs, such patterns are highly sought after by collectors due to their rarity and significance in numismatic history. The "P" mintmark, which stands for the Philadelphia Mint, may appear on some of these pieces, indicating their place of origin.
