Yeah, Ecuador (the 'Quito' gives it away). Is this it?:

Lol, you save a bill for more than 80 years in perfect condition, and it's hardly worth anything.

LOL what was the point! I thought it was worth more than that, Thankfully I only paid $2.00 CND for it and the best part is I got a holder for it. Oh well maybe I will try to sell it to an american for $2.00 US on eBay. Thanks for your help!
