I wanted to know what is involved in having a book reholder'ed. Its not really a big issue (I'm just really picky ) but I recently bought a nice silver age book, graded 9.8, and it has the old style CGC case.   What I wanted to know is if I submitted the book for reholder'ing so that I get the new case, do I run the risk of having it re-evaluated and possibly having the book come back with a lower grade?   K.
