Ironically, there were only a handful of Action and Detective. There is some speculation that some were sold years ago by the original owner as inside a Gerber Photo Journal he had a list of comics which included Detective 27.
When I was a television Sports Photographer I used to go to Williamsport all the time to shoot minor league baseball games. Of course, I would always arrange my time so I could stop at a comic shop or two. One year, a guy told me someone offered him a Detective 27 which looked Fine for 6,700. This was the 1980's mind you. The Comic Shop guy said, "No, that's too much." He never saw the guy again.
So who knows (The Shadow?) whether there was another part which was sold off. I found it peculiar that Detective 27 was written in the book. Maybe it was just a coincidence. They are long gone either way.

I forget what number this graded. Love the cover.
I hope you enjoyed the story. My wife IS a Saint. "Oh honey, I spent our retirement savings on Funny Books today. "WHAT?" "Don't worry Dear, it will all work out." At the time it was quite a frustrating decision to spend all that money. I had never done anything like that before. Of that magnitude anyway.
