They certainly look genuine and definitely early 1963. However as mentioned in the op the possibility of them being a copy is something to consider. I believe the days of 100% certainty from a photo/scan are long gone. Have you looked at them with a loupe to determine if it's real ink etc. When I enlarge your photo I see things I would definitely want to check in person. Especially when I see how good my John, Paul and set was copied.
