I do question the pricing of these items, however. I don't see how everything can continually increase in price from one edition to another, especially when you consider internet sales activity (a very large part of Coca Cola memorabilia sales nowadays). As a collector, I never pay at price-levels shown in this edition, and I certainly do not obtain these prices when I occasionally sell an item off on an internet auction site. I just feel that the prices are a bit inflated. No one could keep track of the huge amounts of Coca Cola memorabilia sales in all venues around the country. I tend to take pricing in guidebooks with a grain of salt, especially, as in this case, when the author is also a major collector. Just a little too much potential for conflict of interest.
