'Respectfully, I don't think any rational human can believe this scenario to be more possible than a forgery."
People seem to forget or ignore the fact that the Catholic Church used this and many other 'relics' to raise tons of money in the Middle Ages via pilgrimages, etc. To "miraculously" find one of these 'Holy Relics' meant lots of moolah to whatever church/cathedral housed them, as they would fleece ignorant believers on pilgrimages to see these 'Holy Relics' out of their money.
Where do people think the medieval Church got all the money to build all those gorgeous Cathedrals from anyways?
Not much of a fan of history are you?
