Although you did not use quotation marks, I interpret your query to state that your amended birth certificate has a notation, "10-9-1968 from albany finalized."
This is not a normal phrase---and I say this after seeing thousands of amended birth certificates. But it is nothing sinister, just an employee who made a mistake.
It would be quite usual for an adoptee born in early 1967 to have her adoption finalized in a courthouse in late 1968, at which time the bureau of vital records would be notified by the court to prepare a new birth certificate.
I think (but am not certain) that the same birth certificate number that appeared on the original certificate would appear on the amended version, but probably typed-in with a typewriter rather than imprinted with a special font.
The "Date received by local registrar" would also be typewritten, while the original certificate probably has it rubber stamped.
The attending physician's name would either be typewritten or signed by an employee, whereas the original certificate would have an illegible signature, just like a prescription.
My comments refer to the full copy version of the birth certificate. The short form version would be a freshly-prepared transcript omitting some of those items. There are various complications to this subject, but I will stop now.
