The Batman #1 issues was last owned by Billy T. Gates who bought it back in 1979 from a comic shop in Houston, Texas for $3,000. Gates sadly passed away back in 2019, leaving his collection to his son.
The issue marks only the third comic to break the $2 million mark with two different copies of Action Comics #1, the first appearance of Superman, both went for over $2 million. One of them being the famed, Nicolas Cage-owned copy. A third issues of Action Comics #1 is still the most expensive comic ever sold having gone under the hammer for $3.2 million back in 2014.
