Collectible coins include various types such as patterns, which are test coins created to evaluate designs or manufacturing methods before mass production. The 1838 One Dollar pattern coin from the United States, struck in Philadelphia, represents a significant issue in numismatic history. Such patterns are often rare and highly sought after by collectors due to their limited production and unique designs, making them valuable for both their historical context and potential for appreciation in the collector market.
