I25068506A is the serial number. Nothing special about it but according to this page one of the smaller runs http://www.uspapermoney.info/serials/f1990_h.html
$100 Frn 1981a I just got 3 1981A $100 FRN's in numerical order. L14467886-L14467888. They look brand new. I am going back to see if they have anymore. 65GT350
I live in a community with very little introduction of new currency. I still find the pre-95 stuff on a daily basis.
i would try to ebay them or take them to a coin shop. you might get a small premium over something like that.
What REALLY annoys me is that a few days ago, I had to pay for a taxi with a '95 F to VF $10. Then I realized i gave the cabbie a 50% tip. It just wasnt my day.
