Also...in the "How to Use This Book" section... The 2015 was published in 2014. Doesn't say which month. Also, there are several factors involved... "data from the listed contributors" - hint: see the list for more info "approximately two months" - hmmm maybe 3, 4 or 1 or whatever "publication" - which is sometime in 2014. So read the book. Be informed.
'Red Book' great for getting info on each variety of U.S. coin, i.e. designer, metal content, mintage & rarity...not so great for ACCURATE value. I also should mention that the latest is modestly priced for a reference book. I would definitely recommend it for any new U.S. collector. J.T.
I agree with Randy. I have a 6th addition and there seems to be little difference from the previous year. Be safe all
