Starting some of the 2003's and newer my paper currency book just says "current". So my question is are their any of the newer notes "current" ones that you keep an eye out for that may not be worth much now but you think may be worth more years from now? Since all my book says is current I'm not sure what to look for and am afraid that maybe I'm missing something that could be of value in the future.
http://www.uspapermoney.info/serials/ will give alot of info. I think it even includes ammount printed for each block.
I would use the website that The Noost recommended. Any star notes with low print runs are notes I would keep an eye out for. Notes with 640,000 printed or even better 320,000.
Ditto and ditto. Look for low printings but keep abreast of it. Sometimes they'll toss in a huge run at the end and make a scarce note much more common.
boy... dont i know it the UsPaperMoney.info web site is great for looking up print run info. i use it almost daily!
