This is a 1983 Unofficial Hawaii State Numismatic Association medal struck by The Hawaiian Mint. It was handed out free to the 1983 HSNA show attendees.

In 1983, The Hawaiian mint moved its operations back to Honolulu and the coin was most likely an advertising piece to get the 1983 HSNA attendee interested in the mint’s products.
