How much more could you cheapen the moment of winning? Hey, great win, here's a replica trophy guys!
I've spoken to multiple keepers of the cup in private settings and know this info. Was lucky enough that on the day after the broduer ceremony when all the trophies were near NYC I was invited to a private party in the backroom of a bar (yes this is real) with the real cup protected by one of the keepers. Even in that setting there were rules with it. One of those was that no one was allowed to lift it. I have also seen a replica at the hall. You can see the differences if you've seen both.
