 | New American Library, which published Mentor Books, used letter prefixes to designate prices. "M" indicated 35¢ books, "Ms" and later "MD" indicated 50¢ books, "MP" books were 60¢, "MT" were 75¢, "MQ" were 95¢, and "MY" books were $1.25. These two scans were contributed by Richard Cohen, of Miami, FL. They depict Mentor MQ771, which obviously was suppose to be sold for 95¢, but a foil sticker was applied to the front of the book changing the designation to MY771, with a corresponding price of $1.25. The spine was left unchanged, so there are now two different book numbers on the same volume. 
 HOWEVER: Here's an email from bookseller Ron Webber that might explain this: 
 On your oddities page, Stickers with 
      Crazy Letters - the reason for the sticker with the MY $1.25 price is that 
      many books imported and sold in Canada had a publisher's sticker with a 
      higher price covering the US cover price because of the difference of the 
      value in the currencies, the Canadian dollar valued at various times as 
      much as 25% lower than the US dollar.   Also, alternatively and most 
      often, the part of the print run destined for sale in Canada had the 
      higher Canadian price printed right on  the cover (no US price at all). I 
      would guess that the sticker was used for titles when only a few copies 
      were exported to Canada so not warranting the extra expense of a different 
      cover printing. In more recent years it has become common for the cover to 
      be printed with both prices (which continues today even those both 
      currencies are about equal).   In the 50 years I have been selling books I 
      have seen these variations thousands of times including the Mentor Picasso 
      title which I believe I have somewhere in my personal collection.  I guess 
      that the Picasso book scans from Richard Cohen are from a well traveled 
      book which found its way from Canada to Florida!  Hope this information is 
      at least a little bit helpful.
