I picked these up today at face value, 7X 1957 silver certificates, 1 1957 *note, 1 1963 red seal $5 dollar bill, 1 $20 2006 star note run size 640,000 total printed 6,400,000 run1, 1 $10 star note 2006 run size 1,920,000 run 1, 1 $5 star note 2006 run size 640,000 total printed 3,840,000 run 6. The silver certificates and the red seal $5 note I know bring very little premium if any from what I researched but the 20,10, and 5 dollar star notes im not sure about. What should I know about star notes? what brings a premium other than fancy star notes? from some things I have read run size 640,000 or less is collectible but do they need to be in gem to bring a premium? if they bring a premium at all. Also the $10 note I posted it has a run of 1,920,00 and there was only 1 run does that make it a little more collectible? I also have been told by another cointalk member that star notes are only worth a premium if they are before 1981 in their opinion. All in all these were picked up at face so im in the good there lol. I appreciate comments and opinions.
