The one thing that stands out to me to suggest that it might be a recent document is that the corners of the document appear crisp. The manner in which the document was folded would likely result in faded corners on an aged document.

Otherwise it looks like a better and more authentic BC than my own.

Yes, but a certified copy could be issued at any time, it’s not the original.

There are signs of wear. The intersections where the paper was folded. and then folded again, have little holes.

However, this brings up a larger question, which may already have been asked and answered in this thread, but I don't have six hours to read all the posts. Here is the question:

Why would someone have kept a folded copy of this document for four decades? No one, other than a parent or guardian, would keep such a thing for that long. If this had been filed in some government office in Kenya, it would have been filed flat, not folded. What is the supposed provenance of this document?
