Kind of a rookie when it comes to paper but I have wanted one of these and a $500 note for awhile now. This one looked pretty decent to me. Maybe somewhere around 30 to 40? Was also called a mule note but I can't tell.
Attractive note! There is always something special about a $1000 bill. :-D This sounds weird, but one way to know if it's a mule is to measure the height of the tiny "8" on the back (far right). That's the back plate check number. If it's pretty close to 1mm tall (a "macro" number size) it's not a mule; if it's close to .6mm (a "micro" number size) it is a mule. A mule carries a very slight premium. You probably know this, but your note is Friedberg catalog number: Fr. 2212-G I'd guess EF-40.
