When my children were born, I was offered additional copies of their birth certificates (at a cost!) by the registrar's office. I thought this might be useful, so I took a few extra copies. Note that these are actual replicas of the originals, along with stamps, watermarks etc. - not just photostats.
Fast-forward 12 years and I recently was required to supply their birth certificates as part of a government bureaucratic process. So, I sent in the certificates that I had carefully filed from all those years before.
However, these were returned to me with the instruction that the certificates had to have been issued less than six months ago. Copies dating from the actual birth dates were not acceptable.
I returned to the registrar's office, ordered (and paid for!) recent copies, sent them in and all was well.
It left me wondering, however, what was the point of this? What fraud could I perpetrate using an original (and entirely authentic) birth certificate that could be prevented by forcing me to get a recent issue?
