I concentrated on the highest grades last year and this year paid more attention to the others. It's not printed on telephone directory paper like Coincraft, but it is already essentially what Rob suggests - a basic volume with values. It contains more varieties than any other coin book and is the lowest priced but I do have to be careful about what varieties are listed as a lot of them just complicate matters. It's difficult to describe some of them in words, so pictures are needed and they take up a lot of space. I don't actually think that making it cheaper (by using thinner paper for example) would result in any more sales. In fact, I don't think thinner paper would actually make it that much cheaper. And especially now that it's available as an eBook for under £5, it's unbeatable value. I think people are suspicious of things that are too cheap. If it was £3 for the printed version, people may imagine that the contents were of little value. Next year I'd like to go back to 1760, so if anyone has some nice images of pre 1797 GIII coins that I can use, they would be gratefully received (and acknowledged in print if so desired).
