I previously owned the current plate coin now used at the Hawaii lop level web page at NGC. I ordered two PhotoProofs. One to held with the coin and the other locked up for insurance purposes.

I still have the PhotoProof certificate of the MS 66 Kingdom of Hawaii 25c in my library. Here is the NGC website link
