Mine also has a raised State Seal and the declaration: “This is a true and correct copy of the official record on file in this office.” Now, that being said, in 1961 the race of the father would not have been listed as “Africian”. It would have read “Negro”. Therefore this is NOT a copy of the original IMHO.
I would investigate whether the group surrounding his number also lists African. That's how I would investigate it.
African at that time makes no sense.
Don't forget Hawaii was a pretty new state so I'm sure they set standards because it was NOW required.
