Roger, I think the other contributors are correct, the first note - is Greek to me! Shows Dr. George Papanikoulaou. The words to the right of his image, what looks like "ARAXMES" is "DRACHMAS" their monetary units, DEKA = Ten, bottom word XIVI... must be "THOUSANDS." The "51" in ink and creasing reduce the bill's value to collectors.

The 10 banknote below, HAROKA BAHKA (that's definitely BANKA) seems to be from MACEDONIA (MAKEDOHNJA).

The Romanians were freakin' out when they designed the next banknote. Romania is the only place where you can get a good Lei.

Honest Abe with red printing may be worth a bit more than face value but again, condition is paramount. Paramount sounds Greek, too. Maybe the Greeks will feature Dr. Paramount on their next bill. Will, I'm off to the Fraternity House to toss a sofa out the second-story window and drink a beer.
