Although few collectors deal in United Nations stamps anymore, I was just on the UNPA website and cropped the "United States of America" flag/coin stamp from their 2013 souvenir sheet:

I was just wondering what the average non-collector would think if this stamp were shown to them. It seems to me that with such a small "U.N." designation in the LL corner, most people would be thinking it was a US stamp.
