The 1907 Patterns are a series of experimental coin designs produced by the United States Mint. These coins were created in an attempt to explore new design ideas and modifications before official minting. The "P 20" designation refers to the specific pattern coin featuring the letter "P" on the obverse side, a mark of its experimental nature. Collectors highly value these pieces due to their rarity, historical significance, and unique designs, making them a desirable addition to any numismatic collection.
