The seal used requires the signature of the HDOH Director
First, a copy of the record.
"a copy attested by the officer with legal custody of the record—or by the officer's deputy—and accompanied by a certificate that the officer has custody."
Second, a certificate:
"The certificate must be made under seal: ... (ii) by any public officer with a seal of office and with official duties in the district or political subdivision where the record is kept."
I don’t know what you’re trying to say.
The letter of verification is to be a certification that the birth facts submitted for verification are as claimed.
The HDOh knew these 3 letters were required to be certified. They failed to do so because the seal they used requires the director’s signature in order to certify/verify documents.
The fact that they refused to issue a certified letter of verification discloses that they have no valid BC on file for Obama. Which makes it clear that the BC published as if it was Obama’s is NOT what they have in the HDOH because it lacks the markings that would show its legal non-validity.
A certifying seal is embossed.
