I was watching a 1997 Princess Kaiulani 1/20 Proof gold on Ebay for a week (sold last night for $145.36). http://www.ebay.com/itm/Royal-Hawaiian-Gold-Princess-kaiulani-1-20-9999-Box-and-COA-included-/262032116634?hash=item3d0254cb9a
What made this coin interesting was its original box and certificate.
Normally, sellers break-up completed sets in hope of obtaining maximum profit.
This princess is undocumented in WIGB. My previous blog https://thehawaiiananumismatist.com/2013/12/15/1997-kaiulani-hapaiwakalua/ . Great item for the Hawaiiana gold collector.
Here are additional gold that one can buy directly from Royal Hawaiian Mint.
I suspect that the above 1997 Kaiulani shares the reverse of this coin. Unlisted in WIGB.
WIGB and M&R indicates mintage of 100. RHM website indicates 65.
