A four-way battle ensued, with the bids at one point leaping from $3.6 million to $4 million, before Robby—and his Jeep—finally sold for $5,375,000. The stellar result means that Robby has knocked the then-previous world record holder—the Maltese Falcon—off its perch. In 2013, Bonhams Entertainment Memorabilia Department made history in New York, selling the Maltese Falcon statuette from the cinema noir classic of the same name for $4 million, then a record price for a movie prop at auction (non-automotive).
Robby was in such bad shape it could sit in the back of my car so you can just imagine because the thing is big. It was just in pieces. Fortunately, [Jim] Brucker had gotten the original shipping cases which were the actual studio cases they used to move him around in. The cases hadn't been touched since the day he got them, so when I went to his storage bin and picked them up, inside was this huge drawer containing lots of spare parts, some of them brand new, that the studio had never used. Fortunately, it was a lot of the stuff that had broken off. I guess they could foresee what would break.
