True. I was there sometime in 2012 or so....funny enough they officially call their currency "Balboas"...and its listed as such on most forex sites.

It was an unexpected trip, so I didnt have time to research, I was rushing around in the airport pre-flight trying to exchange my USD for "Balboas" and the forex guy just laughed and took my 2 x $100 bills and handed them right back and said "poof! now they're Balboas!"
