The top coin below shows you how to locate the Kamehameha I “with Welt” variety from The Hawaiian Mint.
The photo is the obverse from a 1975 Kamehameha I with AG hand stamped on reverse.
The welt is curved raised bump that runs from both sides of the lower dot.
Previously unreported anomalies are the deformed lower dot and a raised spot that intersects the area below the King’s chin and the center of the letter “I” in the word HAWAII.
The lower coin is without the welt.

The 1975 struck sterling silver Kamehameha I – Welt with “AG hand stamped” and no “sterling hand stamp” has a mintage of 6 (note: year on the coin is 1976). This coin type is the 5th listed to be ever struck by The Hawaiian Mint (according to the RHM database).
As a side note, there is another AG version with a second hand stamp of “STERLING” next to the “AG” that was struck in 1976 (it has a mintage of 350).
