Tradition. These are the Faberge egg cognates that I've been working on (Keramish globes). They were made for Empress Nicholle and Cleon IV before the Civil War. During the Civil War, various more or less legitimate emperors sold off many of them. After the war, Arbellatra claimed ownership of all lost Keramish globes but because of the legal mess and because some of the globes were in the possession of powerful nobles (archdukes and dukes), she also established a policy of not enforcing the claim. Because of this the emperors do not, as a matter of principle, buy the globes, but neither do they repossess them. They do, however, tend to be quite generous when they express their thanks for having one returned to them.
Incidentally, I've been trying to come up with various different examples of how that gratitude has been expressed. There's the baronial titles, and I think one younger archducal son has had a death sentence commuted to exile. I've also tried to come up with some pet ducal projects that has received Imperial patronage they wouldn't otherwise have gotten, but I haven't come up with anything good in that line.

First off, let me say that this sounds like an absolutely incredible MacGuffin. The way it is thought out prevents the concept that billionaires can commonly just buy a title. It can also be used in such a fashion as to preclude the concept of the billionaire/pirate just sending someone to steal it. Once it is known to be in someone's possession the Emperor isn't likely to just fork over a title if someone commits an overtly criminal act to obtain it and bring it to him (this doesn't preclude the possibility of chicanery on the part of certain billionaires but it does mean that the actions taken would be more subtle, such as finding out what competitors are bidding if it is a sealed bid auction).
Of course if the ownership of the MacGuffin is not public knowledge then that can lead to all sorts of other games as various teams compete to try and be the first one's to get their hands on in (and then get it back to their employers).
This thing has all sorts of possibilities for how it can me used and its value can even be adjusted through the Emperor's reward (maybe he only gives a Knighthood or a Baronet's title. Maybe there's actually a Barony that for various reasons has recently been vacated and it is expected that the reward could possibly me more than an honor title).
This is one of those plot devices that I look at and wish I had the cleverness to come up with on my own. Kudos.
Secondly, let me apologize if what I'm saying has already been said. I did make it much further than the post I'm quoting but I haven't had the time to sort through every single post on all the pages.
For the 'value' of the object I would try and work out as close to a real world equivalency as I could find. This is obviously really tricky but not impossible. Ask yourself, why is the top bidder interested in this device? Is it purely for reasons of prestige (which sounds to be the case)? Then I would try and find some of the most extravagant 'prestige' purchases made recently (things such as large yachts and planes, works of art, etc.) and use that as a guideline. If it is mostly for prestige but also because there is a certain degree of inherent value (such as the vote, being able to rub elbows with other nobles, etc.) then I might look at prestige expenses that also incorporate a certain amount of utility value. Things such as very expensive houses (where rich people can live as well as entertain).
Keep in mind that the vote or the ability to rub elbows with nobles might not have any worth to your billionaire. Depending upon how rich they are and social conventions they may already be rubbing elbows with plenty or nobles and indirectly controlling more than a few votes.
I realize this hardly gives you the hard and fast values you may have been looking for, but I think it may help you narrow in on a reasonable number better than me just spitting out some result.
