How do you find out by the serial number?
Estimated value of each note is looked up in the Charlton guide to paper money. You can find these at the library and take a look for yourself. Very interesting book with a ton of info.
Is there a specfic website for that?
Not that I know of... that's why some of the unitiated come to this forum
Oh and what if the devils face is in the queens hair. Im sure i see it in there.
Good for you... if the note is in great shape it might be worth something...
