Would a NEW Voynich Manuscript be valuable?

[ReneZ]

I disagree.  The mere fact that it is on vellum and full of purely decorative elements already says that this copy we have was made to be sold, or on commission of someone other than the author.  If it were for the Author's use only, it would have been on paper (still expensive, but much cheaper than vellum) and would have only "technical" diagrams, drawn by the author himself.

The main reason why people continued to use parchment when paper was available and a lot less expensive, is because it was considered to be the more durable material.
The choice meant that the person creating it (or commissioning it - which I doubt) wanted it to last.

Indeed, it would not have just been for personal use, but sale or not does not seem to be decided by this.
