On some laptops, you’ll see the number on a sticker. If you don’t see a serial number after running the wmic command-or if you just can’t turn the PC on or don’t have access to it-there are several other places you might find the serial number:

Find the Serial Number On the PC’s Hardware, Box, or Elsewhere It’ll be in a different place on different PCs, but you can usually find it somewhere on the “Main” or “System” screen.

However, checking the BIOS could be helpful if you can’t actually sign into Windows to run the wmic command. This technique won’t get you a serial number if the wmic command didn’t, since the command pulls the serial number from the BIOS. You may also be able to find the serial number in the BIOS or UEFI firmware settings screen.

This is also true if you built your own PC because the PC itself won’t have a serial number. However, you can look up the serial number of your motherboard and other components.

In some cases, 6.4 million star notes were printed for a particular note, and in other cases only 64,000. Sometimes the note may have a star at the end, and that's where there can be real value. Sometimes these notes have value on their own (as they may be rare or hard to find, ie the aforementioned Large size notes), and sometimes because of their serial number, such as radar notes that read front to back such as 5411 1145 (or a 'very fancy' looking one such as 55000055), birthday/anniversary notes such as 05061977 ('May 6 1977'), repeater notes such as 7411 7411, low serial numbers such as 00000056, and zero ending notes such as 7800000000. These can be both Large and small Size bills (pictured below) from all years ranging from the 1800's to now. People find all kinds of paper money items in a variety of ways including inheritance, in pocket change, from the ATM, in 'grandma's bible', flea markets, etc.
