I recently, for my birthday, got a 2016 Blue Book from a friend of mine. I noticed many differences, like a G-4 Common Indian Head Cent being worth $2.00 in Red and $0.80 in Blue, a G-4 1909-S V.D.B. worth $800 in red and $450 in Blue, and even the 1894-S dime, $1,500,000 in Red and $600,000 in Blue.
