Looks like you have a valuable set there!
I put into eBay search the description of your set, a few sets came up mainly from the States and a 40 piece set listed for around £450 but with a hefty postage charge, and of course there would be custom duties.
Personally, I would list your set as suggested for the minimum amount you are happy to receive in an auction format, as then, you cannot receive less, and if only one bid is placed, you would have achieved the price you wanted.
I would also list it as Collection only, in my humble opinion, it's far to delicate to trust the ' gentle' handling of couriers!
If it does sell and as a Collection item, after purchase and payment you can exchange contact details for collection, but send the buyer a polite message to bring along the 6 digit Collection code, that the item cannot be released without this.
Once scanned or manually entered this is your only proof the item was collected, I would also enter it in the presence of the buyer, to make sure it's entered correctly, showing collection.
Good luck with the sale, it's a truly beautiful item, it will be a lucky winner !
