Those prices are for matchboxes. There were a few cigarette cases in that sale as I recall. Much more expensive than that though I'm afraid. You'll find them on the Sotheby's site. There was a sale inside the past year of Faberge pieces, in London I think, because the prices were quoted in GBP. A quick search should turn them up if you're interested.
Ah, the vestas. Those were usually matched to the case as a set.
