I had to get my birth certificate from PA a couple years ago. It wasn’t a photocopy of my original, it was a freshly printed one with the existing information. So the fact that this certificate doesn’t look like they did 5o years ago does not surprise me. Would seem pretty easy enough to compare it against Birth Certificates back then, and today to point out the obvious differences between the two.
Also, you’d need to have someone with a similar background to see if the PC movement hit Hawaii such that they no longer print new Birth Certificates with the “outdated” terminology.
Which I think all states do. The issue is that all states stamp their seal and an authorized signature on the document. Obama's appears to lack both of these. Apparently Hawaii does this on the back, but it should have leaked through similarly as the date did. There is a certified copy of a Hawaiian Certification of Live Birth posted, and you can clearly see the stamp state seal and signature leaking through. Without those, the document is useless and was not officially released by the state.
