Robert Azpiazu in his book lists the GL first run at $250 and second run at $50. If you are going to get into collecting stars you should definitely get his book (Collectors guide to modern FRN's). However wait for the updated version to include series 2009 to come out later this year. From looking at his book it seems GL*'s came out as replacement notes.
As per prices â€" Only time I have seen recent series notes get near published prices is when they are graded 68 / 69 OR IF it is a fancy sn and then it could go even higher. There are just too many variables that affect pricing and sometimes it's not known for years after the fact.
There are so many choices / ways of collecting star notes that you would have to decide what works for you.
