Circa 1975 / 1976. I’m still pondering the idea of getting the coins certified (NGC to remove the coins from the holder).
As previously identified in an earlier blog. https://thehawaiiananumismatist.com/2014/07/03/the-ag-center-punch-two-varieties/
This Kamehameha Proof set contains the rare (only 6 struck) sterling silver Kamehameha I “with welt”, with “AG” and “NO sterling hand punch” (bottom left).
The bottom right coin is the precursor to the 1998 NORFED silver Liberty “shelter system” design. https://thehawaiiananumismatist.com/2014/06/20/1998-norfed-silver-liberty-first-issue/
In all this is a high demand set by both Hawaiiana collectors and NORFED collectors.
The question is do the other “triangle” proof sets contain the remaining 5 Kamehameha I “with welt”, with “AG” and “NO sterling hand punch?
