I recently read that a 710 year old copy of Britain's Magna Carta was auctioned off for $21.3 Million! Only 17 copies are known to exist.
WOW! That is really something.
But you know what? I can top that! I have the one and only copy of an equally important document that's almost as old.
I have the original "Certificate of Birth Registration" for the infamous BTExpress!
My mom found it while going through some old stuff, so she sent it to me. My actual birth certificate was lost many years ago, so this is something I'm grateful to have.
