Not tru about rarity.... Star notes are higly collectible notes.. I've sold $1 star notes for up to $25 dollars.. The lower the serial number the better, in which your case, you have a 6 digit serail number, which makes it a nicer find.
I've got a $5 Star note series 1999 serial number 00070007* these bills are even worth more. A strange number makes it more valuble, but the combination makes it really rare...
Nice bill put it on ebay, thats where i sell mine...
