Collectible coins, such as the Coronet Head Cents minted in 1836 in Philadelphia, represent notable historical and economic periods. These coins are part of the larger series of U.S. cents, featuring the iconic design by engraver Christian Gobrecht. The "Four Dollars" mentioned may refer to its value in the context of collector assessments or market transactions rather than an official denomination. The Coronet Head design is characterized by a depiction of Lady Liberty, framed by stars and the year of minting, making it a sought-after piece among numismatists and collectors of American coins.
