My advice: save your money and don't bother.

I once popped my head above the parapet with this online survey:
The word "MOG". A decade later, I haven't changed my opinion about the word but am passively tolerant. Normally!
However, I'm currently looking to change my Morgan for a newer model and have found several with "MOG plate included" ... a benefit that typically comes at a £1k-£2k premium! I intend to transfer my current dateless (and decidedly non "MOG") plate to the car I eventually buy so these MOG registered examples are not looking good value to me.
Just my opinion, of course.
