How are the market prices for the Montblanc Skeleton 333 (149 variant) to be classified, and is a mint-condition example for around €10,500 reasonably valued?

The Skeleton 333 had a former shop price of about €7,500; used pieces were temporarily offered for around €3,700 plus shipping, money-transfer fees, customs and import VAT, which gave a total final price of around €5,000 and was at the time regarded as a bargain. In mint condition the collector price is hardly under €10,000 any more, so an offer around €10,500 is to be regarded as market-appropriate.
