Who is known for inventing the dollar symbol in American currency?

The dollar symbol, often represented as $, is widely attributed to Oliver Pollock, an American merchant and supporter of the Revolutionary War. Pollock created the symbol in the late 18th century, during a time when the United States was establishing its financial identity. The design is thought to have evolved from the Spanish peso, which was denoted by a similar script. Pollock's contribution was significant because it helped standardize the representation of the dollar, which became a central element of American currency as the nation developed its economic systems. His innovative approach not only was practical but also played a role in defining the fledgling nation's monetary identity, making it a lasting feature of American financial notation.
