Hi I'm Cynthia. I just started collecting this last year or so. I've got some pretty cool coins, nothing to extravagant. Some wheat pennies those types of things. I got a 1990 hundred dollar bill a while back though in good shape, thats misaligned or what they call "shifted face" I think. I'm curious if its very valuable before I pay the PGC to grade and slab it. Anyone knowledgeable on this? Much appreciated!
