Yes, very sad. 'Check Your Change' was a fixture in the newsagents when I was a late 60s schoolboy. And he had the nous to change the name once decimalisation was done. Having said that, my 1979 edition of CCGB is very much a CYC-type pocket booklet, though with ever-more useful bits of information added with every issue. Even by 2000, it was still very much a booklet, though by then it had evolved into the A5? landscape format. It was cheaper than Coins & Market Values, and IMO far better though it didn't go back to early milled. I never met the man, but he must have had a deep passion for the hobby.
