I keep a few bills with 8s and 9s as they're very lucky numbers in the Chinese culture. Here's a list of what I've kept: $20s: Devil's $20: IE 6266656B Lil Devil: IF 6869661F Lucky 7s: IJ 07778828A EL 11110398A EC88885403C GF00433962* (star note) IL 40730001C EL 05381074* (star note) GE 88458928C IF 29642999D $10s: JL 19888574A 1950 $10s: 1) L82684898B B series 2) L51101455C C series 3) L74482136C D series $5s: JF 51586999B seems some 9s are crooked IG09929529C JL 58005550A ID 9199092A $1s: my favorite silver certificate: 1935 A01117711I 80688383 89588287 95597989 4184444 00314768* (star note) 02803586* (star note) 11211132 60002820 67705566 57976567 0044375 got tired at the ned. just wrote the serial #s. now, my hands and eyes hurt...lol.
To research the blue seals yourself for scarce letter blocks here's the link... http://apdcurrency.com/db5/00457/apdcurrency.com/_download/BlueRedGoldGreenSealsMasterversion4.pdf Are all the $1 blue seals or are the rest green seals? Most of the "lucky" money starts 777 or chinese 888 or 168 for luck forever or something like that. Don't know of any 999 other than it being lucky (as it's close to a natural 9) for bacarat players much like horse racing and $2 bills now if there were more 9's like 99999997 toward the end of a run aka high serial number you are talking interested people. I don't know of much premium for those numbers in the middle or ends of the serial number. Another thing to look for is like on the $10 starting 1988 if the series was a 1988A (even better if the block was A1988 on a series 1988A) but the double letter at the beginning suggests it's a 1995 series or newer. As for keepers my picks would be definate one's that are uncirculated no folds, creases, stains, nice sharp unbent corners, etc. the star notes, the 1950's series $10, the 0777, the 8888, would need pics on the crooked 9's as that may be a printing error, I would also be curious on the two $1 notes that don't have 8 numbers only 7. Make sure both serial numbers are the same on the bills that's an obvious error most overlook. It's called mismatched serial numbers. Another one that goes undetected sometimes are notes that are missing printing such as seals, signatures, etc. The other thing you might want to research is modern scarcities. The 2004A series $10 star note from the chicago (G) district is an example. There were so few stars for that district that for a modern bill they are already worth $60 I know I got lucky went to the bank and got one when I cashed a check. Dumb luck but I'm not complaining. If you can get a copy of a magazine called paper money trends it will help you out. It has grading instructions for notes and ball park pricing it's the cheapest option put out by the coin world folks. Other more expensive options for currency are the "blackbook" of currency it's to notes what red book/blue book are to coins, or there is a whitman publishing book on bank notes "A Guide Book to United States Currency", for errors I recomend the "United States Paper Money Errors" book. Those should give you some info if any of the series or blocks of notes you have are a treasure. Good luck.
