This is, of course, a quick 'n' dirty ID. Don't make any investment decisions based on my advice--you might have enough here for a few tasty adult beverages at your local watering hole.
The top three are banknotes, and actual ID will be based on presence or absence of grills, secret marks, and paper type. 206 is also a banknote, but I'm calling it a 206 because it looks like the frame lines are thin and spindly, characteristic of this re-engraved number compared to earlier numbers.
Mystic stamp has a good online catalog which can be used to get values. Catalog values, of course, are pure fiction. You, as seller, will never get it. You, as buyer, would be foolish to pay it, IMHO.
