What is ZL-1 # 51 worth today?

[COPO]

At this year's BJ auction, I think ZL-1 #51 was bid to ~ $800K, but I heard the sale went bad due to questions about the originaliy of the engine block. Reggie Jackson owns the car and recently came to GA to visit Lamar to find out about the block. There is another thread on the board that discusses this in more detail.

The car Bruce posted was a virtual twin to #51, but was an iron block COPO and was also originally owned by Lamar. He sold it prior to 2005 though. It was offered by a member of this board in the for sale section a number of years back. Great colors.
