They were still selling these - only without the "1976" date - when I passed through Honolulu Airport in June 1983. The undated example in the OP's Numista link is the same as mine.
Mine came in a little acrylic case with a black plastic insert and is still in quite good condition, but I have seen similar Hawaiian tourist dollars that were sold in PVC flips, turned green by the storage conditions.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
