Collectible coins encompass a wide range of numismatic items, including historically significant pieces, patterns, trial coins, and more. Patterns are prototypes or trial pieces struck to test designs or minting techniques, often produced in limited quantities. The 1822 trial coins are notable examples, as their rarity and historical context increase their desirability among collectors. Unknown or ambiguous provenance can significantly affect the value and interest in these coins within the collectible market.
