Medcalf & Russell states that the mintage is 921,622. Is that mintage figure correct? Not really…
This medal is also listed as FMR-PL01 in my book, The Hawaiiana Numismatist’s Catalog of Franklin Mint Issues Relating to Hawaii. http://www.amazon.com/Hawaiiana-Numismatists-Catalog-Franklin-Relating/dp/1496144821/ref=sr_1_1?ie=UTF8&qid=1408672878&sr=8-1&keywords=the+hawaiiana+numismatist
Actual mintage is 21,622 as indicated in my book (based on actual Franklin Mint mintage figures).
Intact medals in original postal cover is highly sought after due to its stamp and postal cancellation. This is a First Day Cover highly prized by philatelist (stamp/cover is cancelled with the date it was officially released by the US Postal Service). The medal and COA (reverse side of envelope) is highly desired by Hawaiiana numismatists. However, when a specimen with COA also comes with its description card and original Franklin Mint album page, this is the most desired collectible state. Below is such a specimen that is in my collection.
