I have a very busy blog website (TheHawaiianaNumismatist.com) and get many requests relating to Hawaii coins, medals, and tokens.
I am tracking down a NGC point of contact for high resolution images for the Smithsonian National Museum of the American Indians. (They have periodically held Hawaiian events and displayed Hawaiian culture items). They are seeking specific images of Kingdom of Hawaii coins.
Contact me ASAP with NGC point of contact so that I can forward it to my Smithsonian contact or email for the Smithsonian contact email address.
Message was also posted on the message board being monitored in ASK NGC.
