I'm still adding to my library of coin dealer premium guides, and the latest acquisition is this little booklet from Stack's in 1936. It's very similar to the dozens of such guides put out by dealers during the 1930s, but it does include a feature I've been seeking for awhile.

Walter Breen and other writers have commented on how dealers declined for years to buy certain USA coins that were just too common, but this is the first time I've found printed confirmation. The inside front cover of this Stack's premium guide clearly states which pieces are NOT wanted. A previous owner had at one point crossed out the word "NOT," but I've been able to restore it to readability. Note also that he protested the company's policy of changing prices by adding the words "Without Notice!"
