The US 11-sided coin is known as the "Susa." It was introduced in 1792 as part of the early American coinage system but was never mass-produced or widely circulated. The coin was intended to have an 11-sided shape to help distinguish it from other denominations and prevent counterfeiting. Ultimately, it is more of a historical curiosity than a common piece of currency.
