Have no fear. You are quite unlikely to ever see your original birth certificate, which is probably stored somewhere in Jefferson City, if you were born in Missouri.I don't have my original birth certificate, I'm a little worried I might have been placed as an infant as a communist plant.
Few Hawaiian officials have ever seen President Obama's original birth certificate, but the Director of Hawaii's vital statistics has signed a certification that she has. "Birth certificates" are always copies of the original birth certificate, regardless of whether (in Hawaii) there is a "long form," or a "short form." I have in my possession two official birth certificates. By far the more interesting one is a negative photocopy, with a raised seal and a certification. This certificate shows the original signature of the attending doctor.
