As a member of the “bust halve” series, this coin is considered part of the “true heart of United States coinage” from the “peak” era of silver coinage. Like many of the earliest coins, the capped bust halves were struck with screw presses that often required manual design input which in turn created a veritable plethora of unique strikes. As with almost all United States coinage, this too went through a few modifications throughout production that resulted in several subtypes. Part of the intrigue this coin holds, beside the subtypes, are its various die varieties that keep collectors on their toes and truly demonstrates the diversity of the earliest American coins. Additionally, this particular Capped Bust proof coin- along with its 3-5 siblings- were minted the same year congress officially adopted the American flag in 1818. Meant to be a strong symbol for the Nation, the accepted flag bore thirteen red and white stripes with a blue field of stars to represent each state. Prior its acceptance, Mississippi had just been admitted into the union as the twenty-first state, so the flag donned twenty-one stars. Giving this coin a unique perspective in relation to American history as well as adding to its incredible rarity.
