Why is the SBA dollar coin called the Carter quarter?
The SBA dollar coin is actually a misnomer, as SBA stands for 'Susan B. Anthony dollar coin' and not related to 'Carter quarter'. The coin was named after Susan B. Anthony, a prominent figure in the women's suffrage movement. The term 'Carter quarter' seems to be a misconception or possibly a regional slang, as it is not an officially recognized name for any U.S. coin.
