Coin Book Question

I have everyone made. Not sure about that one but I remember many years ago someone told me about a missing page in one. Normally I never open them but I did this time and a page was missing.
Makes no difference since I never sell coins or the Red Book so values of ether are irrelevant.
If you have the 2011 edition this is covered on the top of page 409. No value but they mention the missing page 237 and a page 239 is duplicated.
On the bottom of page 408 there is a little info about other oddities and their approximate values of that book.
Also, in the top paragraph on page 409 there is that reference to the book about this book produced in 2009.
I wonder if Whitman will make addtional editions to the one that explains all the other Red Books and then they would need a book about those too.

Just thinking as I read this, coin collectors are quite an interesting bunch. The fact that some collect the collectors books.... I do see why some people give me the look they do when I talk about my coins.

Still love the hobby
