I was hesitant to purchase Luckey's 12th Edition Price Guide because I have always relied on Robert L. Miller's No. 1 Price Guide in the past. However, curiosity got the better of me and I'm glad it did. It's a great reference, and a very good companion to Miller's guide. The main advantage Miller's 10th Edition No. 1 Price Guide has is all figurines are now shown in color... but the images are smaller than in previous editions. Since Luckey's guide (updated by Dean Genth) is presented in a larger format, it has larger images and text, which makes it easier to read. It also displays more images of the older trademark figurines to show the differences between the older figurines and their current production versions a bit better. This was important to me because I generally prefer to collect the older, more rare figurines.
Figurine pricing is now essentially the same between the two guides, which isn't surprising considering Dean Genth owns Miller's Hallmark in Eaton, OH, the home of Robert Miller.
For the average collector, or one that usually tends to purchase the newer released items, Robert Miller's guide is now more up to date. However, for the truly serious collector, Luckey's guide has more or different information on some of the more rare figurines such as those made in white overglaze and sold only in Belgium in the early days. Since I own several of these figurines, I found the information contained in Lucky's guide very useful.
Highly recommended for both the novice or serious collector... but don't forget to purchase Miller's book too.
