This is one of the most popular denominations of bills here. It's the 100 peso note, or the $2.22 note as I like to think of them.
All foreign currency is interesting to me but this bill has the US flag directly on the bill with the Philippine flag.
All of our history with the Phils is not great but most of those that I meet here are very friendly to Americans, American products and ideas.
Just imagine the uproar if there was a Brit flag on any of the US currency!
