Redbook Changes Over the Years

I'd like to start a new thread and this likely could become a sticky, tracking thread, or whatever you want to call it. The purpose of the thread is to track changes made in the Redbooks over the years. I, for one, face the daunting task of trying to spend time comparing this year's Redbook with last year's in order to see what price changes have occurred. In general, I'd like to forget about insignificant ones. If an older Lincoln penny in AU went from 10 cents to 15 cents over the last year, I don't really care. But if the price of a 1909-S-VDB went up by $100 in VF, I'm interested.
And the changes don't have to necessarily be price related. For instance, shortly after the mintages for the 2009 nickels and dimes were included, I noticed in the 2014 Redbook that the 2009-D nickel had a mintage of 468,000,000. I remember writing to the folks at the Redbook and they subsequently changed it to the correct 46.8 million figure. Note that in 2013 they had the mintage correct, but somebody added another zero before the 2014 edition was printed.
I will mention another item that I saw a while back. In the 2014 Redbook all of the 1905 Barber quarters went up sharply in value, even in just Good condition. Look at the following changes:
1905-P 2013 = $14...2014 = $30 (up 114%)
1905-O 2013 = $18...2014 = $40 (up 122%)
1905-S 2013 = $14...2014 = $30 (up 114%)
Does anyone know what triggered more than a double on the prices for the 1905 quarters? I figure that perhaps someone influential (like perhaps Q. David Bowers) wrote a book saying that the number of coins still around that haven't been melted, etc. was quite low. I'd love to know if someone else has a good theory about this one.
I remember buying some of these very cheaply shortly after the increase occurred. It seems like lots of people had no idea how much they had gone up. FYI- Those prices are still the same in the 2020 Redbook.
For me to include all my thoughts on this topic would take some time. I don't want to waste my time unless there are plenty of others here who still are interested in the Red Book and still use it. So, my question is- How many people would like to see this type of discussion thread?
P.S. For those who are early in the stages of their coin collecting days, the Redbook usually comes out about April. So the 2020 Edition was available in April 2019.
