Bud Meyer found the JDH chips. They came from an estate sale. There is plenty of info on the internet about John H Dollar, Dollar Steamship Line, his family, and President Cruise Line which still operates today. I've been on over 100 cruises but never sailed President. At least than I can remember.

In the past I have been known to send this type of chip to Steve Passalacqua asking if it was a "Die Cut" or a "Reverse Die Cut." I guess he got tired of the emails and sent me this. Thank you Steve.
