When and where was the first US quarter made?

Answer 1

The first US quarters were struck in 1796 at the Philadelphia Mint.

MorePhiladelphia was the only US mint until 1838.

The 25¢ denomination was created as an exception to Jefferson's plans for a fully decimal coinage system based on multiples of 2 and 5. Spanish pesetas were commonly used in colonial times and remained legal tender in the US until 1857. They were divided into halves, quarters, and eighths rather than tenths. To coordinate change-making between dollars and pesetas, the US system adopted a quarter-dollar coin instead of the 20-cent denomination typically used in pure decimal systems.
