Never seen this one before, only thing I know is that it's 5 ounces and only 10,000 of them were minted. I loved the design and had to have it! Sniped it for $100 bucks
Not bad. Only $2.05/oz over melt, and it's .999, so you shouldn't take much of a haircut when you go to sell it even if you don't find the right buyer. One went for $125 plus $5 shipping on eBay two weeks ago.
Nice coin! A few more details are here: https://en.numista.com/catalogue/pieces52947.html And NGC price guide has it at $185 (I believe they use Krause), but you shouldn't really count on that as being any indication of the true value (as you have already seen by the average ebay selling price): https://www.ngccoin.com/price-guide/world/pitcairn-islands-50-dollars-km-5-cuid-33010-duid-96456
