That was me! I did that. Idea, author, editor and publisher! I knew that it would kill 3 birds with one stone, so to speak. 1. Encourage new collectors' with a free coin, the likes many would never have seen. Like you say, the young collectors are the new generation. 2. Encourage sales with a free gift, and the only book of its kind with a free gift, and 3. Allow me to get shot of thousands of 1966 halfpennies! (I have another 2000 standing by) It seems to be selling quicker than previous editions at this stage. In what shop did you see it? WHSmith haven't ordered any from me yet, which is a pity as they might not be in time for Christmas at this rate.
