In the realm of collectible coins, "patterns" refer to trial strikes or experimental designs created to evaluate the aesthetic and functional aspects of new coins before their formal adoption. One notable example is the 1878 P 5, a pattern coin created during the transition to the Morgan dollar series. These coins are highly sought after by collectors due to their rarity and historical significance, often featuring unique designs that differ from standard circulation issues. The United States Mint produced these patterns in limited quantities, making them valuable additions to both numismatic collections and investment portfolios.
