How much is a Panamanian dollar worth in the US?

Answer 1

There isn't a "Panamanian dollar". Panama's currency is called the balboa. However, the US dollar and Panamanian balboa are linked to each other at a ratio of 1-1. That is, the two currencies are worth exactly the same in the international exchange market.

Answer 2

You exchange currency from one country to another rather than "turn it in".

The Panamanian balboa is linked to the U.S. dollar at par, so $1 = 1 balboa.
