Star or replacement notes are special U.S. Treasury-issued bills used to substitute misprinted or damaged currency. Instead of reprinting the original serial number, these replacements feature a small star next to the serial, marking them as substitutes. Produced in smaller quantities, star notes are rarer and often more valuable to collectors, especially when issued in low-production series.
