The Cash Scramble: Why Millions Are Suddenly Checking Serial Numbers on Everyday $1 to $20 Bills

Learn why The Cash Scramble: Why Millions Are Suddenly Checking Serial Numbers on Everyday $1 to $20 Bills remains a key topic with our thorough coverage.

Alongside numbers, symbols matter. When a flaw, tear, or ink smear occurs during the high-speed printing process at facilities in Washington, D.C. or Fort Worth, Texas, the government removes the damaged sheet. Because printing two bills with the exact same serial number violates federal audit rules, the facility prints a replacement run.

These replacements carry a small five-pointed star adjacent to the serial number in place of the customary suffix letter. The presence of that mark sends hunters directly to an online star note lookup tool. Star notes represent replacement currency, but not every star note yields a cash premium.

The determining metric is run size. The Bureau of Engraving and Printing issues replacement notes in standard batches of 3.2 million bills, alongside short runs as limited as 640,000 or 250,000 notes. A star note from a 3.2-million run carries almost no collector markup in circulated condition. A crisp, uncirculated note from a 250,000 short run can easily trade for $20 to $100, even with unremarkable serial numbers.
