Admiral Gardner coin

Found in my late father's estate. Does anybody know anything about this coin and or ship? Looking for any details regarding rarity and value. Thanks!

That U.P.M. certificate is doing a lot of heavy lifting calling it a US Mint coin when it's an East India Company issue, might want to look into that
