The coin itself, a half dollar minted for circulation, but also minted to commemorate the recently deceased president, is common. The holder may not be. It apparently was created to hand out examples of the half, as Coinbuf stated, to customers, etc - in this case, foreign customers. Pretty cool find, in my opinion.

Thanks! Yes, it was given to my grandpa, he worked at the Bank of Costa Rica 

 I found this coin recently and believe it's farely important. I don't have any knowledge about coin collecting and want to know more info about it. 1964 John F. Kennedy Half Dollar
