Not that kind of xxx! https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/324056391148 If I had that capital at the moment I would be so so tempted.
Answered with a quick Google, there were a small batch of xxx/500 bikes dispersed globally so by no means unique and were Press / Demo bikes, seem to be regarded as second class citizens to the numbered bikes.

History shows in every case earlier Pre Production bikes will be worth more than production bikes in the future - here is a pre production (not even a prototype) CB750 Honda. Probably 10 times the price of a Concourse CB750 K0 and it's a pile of scrap... https://newatlas.com/pre-production-honda-cb750-usd263725-world-record/53667/
https://www.ebay.co.uk/itm/324278019461 This is back on the market. If you were buying to use it, its a great way of saving £10k.
I would need 10 times my current income to even consider it. What did they cost new? £50k? Not a great investment in all honesty. Imagine how good you could make an 1199 by buying one secondhand for £10k and then spending even just another £10k to make it better? Saved - £15K I'm happy that these bikes exist, but its not something that has any buying appeal to me.
It was in @cookster garage at Silverstone. JHp customer. Belive it started as an SL2 until and unfortunate event
