Yes, see my response on post #93.
The year group on the computer-generated abstract "Certification of Life Birth" has 4 digits (Y2K compliant) for the year the person was born; the "Certificate of Live Birth" (long form) has 2 digits for the year.
That's what Obama is hiding -- his "original" birth certificate.
The serial number is called a “file number” on the form, and probably refers to the order in which the document is filed by the registrar. The key thing to note is the dates of birth, and the date of filing.
If the number is assigned at the hospital (Kapiolani) then nothing can really explain why they would give Obama the high number and then give the twins the lower numbers.
If the number is assigned when it is filed at the registrar, then they would have to have skipped over the twins from 8-8-1961 when Obama’s was filed until 8-11-1961 when the twins were filed. The twins mom didn’t sign it until 8-7, and the doctor didn’t sign it until 8-11, so it didn’t leave the hospital until at least 2+ days after Obama’s had already been accepted by the registrar (according to his factcheck short form abstract).
The twins certificates could not have been part of the same “batch” at the registrar’s office because they were necessarily transmitted from the hospital to the registrar days after Obama’s had already been accepted.
If, however, the “batch” processing happened at Kapiolani, they would have had to pull the serial-number-stamped blanks out of order.
It would be nice to know where and when file numbers were stamped. It had to be either before the papers went to the hospital, or after they came in to the registrar. They couldn’t be stamped at the hospital, because hospitals all over the state couldn’t keep from accidentally duplicating.
