United States Banknotes
Special Serial Types
This page describes the various special (aka Fancy) serial types that the united states banknote checker tool looks for on your U.S banknotes.
Serial types listed above will have an example and statistics available based on a maximum print-run of 99,999,999 notes, serial number 00000000 is ignored as this is generally reserved not for circulation.
If you collect a serial type not listed above and would like me to add it to the checker tool please Request A Type below.
ALL UNIQUE DIGITS
All unique digit serial numbers will not have a double up of any of the digits shown in the serial number.
Binary serial types consist only of 2x different digits.
Serial numbers that consist of only ‘0’ and ‘1’ digits are known as True-Binary serial types.
Birthday serial are a serial number that can be read as a date, they are generally collectable if they happen to match a famous birthday or a significant date.
The checker tool identifies birthday serials with the following formats:
MM / DD / YYYY
YYYY / MM / DD
*Note* The checker tool limits birthday serials from the year 1776 though to today, it does not identify earlier dates or future dates however these serials may still be sought after.
Bookend serial numbers have a matching block of digits on either end of the serial number.
Broken ladder serial types consist of all the digits of an 8-Digit ascending or descenging ladder, however the digits can be in any position and do not need to have a full run in consecutive order.
The higher the serial number the more desirable a note is for the high numbered serial type.
The following high numbered serial types are:
Single Digit: Serial # > 99999990
Double Digit: Serial # > 99999900
Triple Digit: Serial # > 99999000
Quad Digit: Serial # > 99990000
Ladder serial types are where each following digit is either consecutively increasing by 1 number, or consecutively decreasing by 1 number.
The following ladder types are defined below:
Ascending Ladder (Asc.): A streak of consecutive increasing digits, ending with a maximum digit of ‘9’.
Descending Ladder (Desc.): A steak of consecutive decreasing digits, ending with a minimum digit of ‘0’.
Run-Through Ladder: A streak of consecutive or decreasing digits ignoring the maximum or minimum digit break.
*Note* A block of ascending or descending ladder serial type can be at any position of the serial number if less than an 8-Digit type
The lower the serial number the more desirable a note is for the low numbered serial type.
The following low numbered serial types are:
Single Digit: Serial # < 10
Double Digit: Serial # < 100
Triple Digit: Serial # < 1,000
Quad Digit: Serial # < 10,000
Near-Solid serial types are 1 or 2 digits away from being a SOLID 8-Digit type.
The off-solid digit(s) can be located at any position throughout the serial number.
Radar serial types have a block of digits that read the same from left to right / right to left.
The block of digits can be at any position throughout the serial number if less than an 8-Digit type.
Repeater serial types consist of 2x matching blocks of digits.
The blocks of digits can be at any position throughout the serial number if less than an 8-Digit type however must be adjecent to eachother.
Rotator serial types are serial numbers that can be read upside-down.
Rotator serial types are fairly controversial in what qualifies as collectable.
The following rotator types are defined below:
Soft-Rotator: Consists only of digits ‘0’,’1′,’6′,’8′ or ‘9’, digits can be in any position throughout the note.
Soft-Rotator (Strict): Consists only of digits ‘0’,’6′,’8′ or ‘9’, digits can be in any position throughout the note.
Super-Rotator: Consists only of digits ‘0’,’1′,’6′,’8′ or ‘9’, Must read as the same serial number when read upside down.
Super-Rotator (Strict): Consists only of digits ‘0’,’6′,’8′ or ‘9’, Must read as the same serial number when read upside down.
*Note* Strict Rotators do not include the digit ‘1’ as the font does not look identical when upside down.
Semi-Solid serial types consist of only 2 digits, starting and ending with unbroken streaks of either digit.
*Note* The larger streak block can be of either side of the serial, eg: 11222222 or 11111122 are both (2-6 Digit) types
Solid serial types are made up of serial numbers with an unbroken streak of matching digits.
The unbroken streak can be at any position throughout the serial number if less than an 8-Digit type.

I have a $10 bill with a serial number of NL 63873737 A.
Ten dollar bill NA11668899A Four pair together the bill is not in good shape
Have a $20 US Bank note 2013 series serial number
MA 38898999 B I’m just curious if it’s worth keeping or if it’s a common bill And just go ahead and spend it i’m very new to collecting so Any information would be very much appreciated.
thank you for your time and this website.
I have 9 in a row subsequential $50.
Is there any significant value for them being all in a row or would they be of face value. Ended up getting them from an ATM and have 2 more sets of subsequential $50, more than 5 in each set. No
I’m interested in finding out more about how some numbers are bolded more than others. How some numbers are raised higher, or how some digits are bigger than the other numbers.
I’ve got a few bills,
First one: $1 w/ serial # J65855553A
Second one: $1 w/serial # L83035393A
Final one: $5 w/ serial # PL39936645A
However I’ve also got two more that have what I’d consider broken ascending/descending…. here’s what I mean
40749586 & 42189675.
As can be seen in each here, numbers 4, 5, 6, 7, 8, & 9 are broken/ not in succession, yet still very present!! To top them off they are both dividends of $5 each!
With all that, do I have anything worth by effort?
I have a five dollar bill with the serial number
I hope someone can help me. I have a 5.00 bill with the serial number PH00600600A
IN GOOD CONISTON
Hello I have a 1$ bill with a serial number of E 44444880 C…. Was wondering how much it would be worth? Thanks
I have a $20 number is ph05888888c
What can you tell me about it? Solid???
All even and all odd serial numbers should be included. Examples 86040666 or 17955713. Only .39% of 8 digit serial number have a combination like this. That’s an availability of 389,999 of 99,999,999 which is less common and more unique than several of the fancy serial numbers you have listed above.
Need to add the trinary. Example 66686388. They’re genuinely unique looking serial numbers. They rank high on the fancy serial checker as only .71% of 8 digit numbers have 3 or less unique digits. So out of 99,999,999 only 709,999 x available. Which has a similar quantity to 4 digit ladder and It’s less common than 2 digit book ends and all unique digits.
Hi Samuel, Thanks for the suggestions and stats, will add the details into the tool in upcoming update
Hi I came across a 2018 $50 general prefix 2/2/2 repeater (6-digit) binary (6-digit) the serial number is GI180181818 can you help with a value on that please.
