A regular Hermès Birkin bag is worth thousands of dollars. But the one that started it all, Jane Birkin’s original prototype, sold for 8.6 million euros at Sotheby’s Paris, or $10.1 million, setting a new record for a handbag sold at auction.

A lively bidding war led to the Hermès prototype, which was created for the actress Jane Birkin, selling for far more than expected.

The original Hermes Birkin bag, custom made in 1984 for British actor Jane Birkin was sold for $10 million private collector in Japan, said a release by Sotheby, an auction house. Birkin bags are luxury handbags made by the French fashion house of Hermes. Each bag is handmade by a single artisan using premium materials.
