Check the listing for details. 1939 Golden Gate Exposition HK485 So Called Dollar Treasure Island Ex. Rare. Listed at 495.00 USD. THe Original Hibler & Kappen book calls this issue Extremely Rare with 5 to 20 pieces known but I do not think it is that rare but it is still a highly desired item for the So-Called Dollar collector. I graded this to the best of my ability but I am not a professional grader. Use the photos to determine the grade to your own satisfaction and you are welcome to ask questions if I can help. Your satisfaction is guaranteed. If you do not like your purchase for any reason you are welcome to return it for a refund. A portion of the proceeds are given to a home for children which does not rely upon government funding. It is a very worthy cause run by professionals and highly trained specialists who work especially hard to transform children in need of serious help into happy, functioning adults of tomorrow. To give a little through a simple purchase is to give a lot to those in need.
