In 1836, the United States Mint in Philadelphia produced a series of trial coins known as patterns, which were experimental designs for the One Dollar denomination. These patterns were created to demonstrate potential coin designs, often featuring innovative artistic elements and obverse and reverse configurations that differed from standard coinage. The 1836 dollar patterns are particularly significant among collectors for their historical value and aesthetic appeal, with some variants showcasing intricate designs like the iconic representations of Liberty. These trial coins are highly sought after in the numismatic community due to their rarity and the insight they provide into early American coinage experimentation.
