I have googled and goggled all day and can't seem to find any listing of coins shows in Hawaii. Any info would be very helpful. Mark
http://www.coinshows.com/hawaii.html There's a little generic information here. It looks like 3 coins shows. You may want to contact the groups mentioned for precise dates. The HSNA has a spring show. There is an HCC Statehood Day Coin Show in the summer. And on Waikiki the HSNA has a fall show. I can't really find much information on these organizations, but here is an article about one of the past coin shows. http://www.numismaticnews.net/article/Scout_record_set_at_Hawaii_show/ Try checking the phone book for coin dealers and asking them about coin clubs or about the coin shows. They should have more information. Have fun!
There is also a thread on here by Stainless, I think, that lists shop shops around Hawaii. Here it is http://www.cointalk.com/forum/t38604/
