I have legal tender with this name on it. Serial number 21A 564241. The bill also has 100 on it. I am trying to find it's worth and where I can take it to get US currency.

Greek? 100 Drachmas? 35 cents US. Nobody will exchange it for 35 cents.

If its an old European currency and pre-Euro (any country using the EURO now), it only has collector value.. which is minimal.
