For those of you on Oahu or planning to visit Oahu here is a purchase tip for a 26 year old silver medal struck by the Honolulu Mint in Mint Condition.
Go to the bottom right of the page from the link below (see that shiny medal for $25 ?).
This is the reply from the school (May 2016).
You need to check if you can actually go on campus during the school year to make the purchase. http://www.mckinley.k12.hi.us/
