Dollar Bill Serial Number Trick

Fancy serial numbers are what PMG refers to as “special” serial numbers — solid digits, radars, low serial numbers 1 through 10, etc. They are pouring in from all over the world. This article will describe the different kinds of fancy serial numbers that we recognize. A quick definition of each fancy serial number will also be given.

­All modern United States currency contains either a 10- or 11-digit serial number in order to make each bill unique. Ten-digit serial numbers were on all bills until the 'new style' came out in 1996. Those bills (and all produced since then) have an 11-digit serial. The serial number consists of the following:

  • The first letter, only found on the new-style bills, represents the series of the bill. The series indicates the year in which the design of the bill was approved for production. This begins with A, and moves through the alphabet each time a new series is needed (for example, each time there is a new secretary of the treasury, the bill design changes because the secretary's signature is on all currency). You can also find the series of the bill printed directly to the bottom-right of the portrait.
  • The second letter (or first, if you're looking at an old-style bill) represents the district of the Federal Reserve Bank that your bill was issued from. As there are 12 Federal Reserve Banks, this letter can range from A to L, with A representing Boston and L representing San Francisco.
  • The eight numerical digits that follow represent a unique ID number. This number increases sequentially as each bill is printed. Using these digits alone, there would be a possible 99,999,999 bills issued per bank.
  • The final letter is used to raise the number of possible bills beyond 99,999,999. Altogether, there are a possible 2,499,999,975 serial numbers for each bank!
  • After that warm-up, the naming of the bill's serial number digits commences - using an entirely different code! Dollar bills' serial numbers begin and end with letters of the alphabet, and these can be coded as were the names of objects above.

  • A super radar number is a radar number with all the same interior six digits. Numbers like 10000001 and 011111110 are examples of radar numbers and sought after serial numbers of $1 bills. Think of ladder numbers like a sequential pattern. Every number is either one lower or one higher than the previous digit.

On occasion, a bill shows up that has a small star in place of the final letter in the serial, and many early issues carried the star in front of the serial number.

This star represents what is known as a replacement note. When a printing error occurs during a normal press run and renders a set of bills unusable, replacement notes are used instead. With replacements notes, a set of serial numbers can still have the proper number of bills even if some of the original bills had to be pulled. The replacement notes have a sequence of their own, using the star as their final 'letter.' This allows for 99,999,999 possible replacement notes for any given bank, series and denomination. This should be more than enough: According to the Paper Money Collecting FAQ, there's about one error in every 100,000 U.S. bills.

In general, replacement notes aren't worth more than regular bills. However, if you find a replacement note with a particularly interesting serial number — like 00000001 or 999999999 — or a large number of consecutively numbered replacement notes that you keep together as a lot, you may have a collector's item on your hands.
