No, valuable was exactly the word I wished to use. My comment was facetious to the extreme. I used valuable because that is what has been claimed over the years in posts and comments more times than I can count. There is a huge group of people who actually believe that having a coin slabbed makes it more valuable than it would be raw. This belief is absolutely not true !
