Rather already noted that using either for pricing is impossible. The Red Book
is being sold already in April of one year and dated the following year. The 2011 has been out for about 6 Months now so unless the people at Whitman
can forsee the future, any price they put on a coin is just a guess. The Blue book was orignially supposed
to be the lowest possible price a coin should, could, might, would, etc sell for. The Red Book
to be the highest possible price. Both are impossible unless they can forsee the future.
I think the really main difference is many people collect the Red Book
but I've never heard of anyone collecting the Blue Book.
Another important thing to note is the Red Book
now comes in a larger size for us old people.
Also, a ringed version for those that don't want to bend the pages. Now that if versitility for you.
I'm sure there will soon be a key chain variety too.
