I recently submitted over a dozen comics for screening, pressing and grading. Being a newbie as far as grading and estimating a value of my comics, I assigned values to some of the rarer comics that may be more (or less) than the current market value, based on whatever the final grade is.
My question is, "How does CGC charge (or refund) for differences in estimated value versus the CGC-graded current market value of a given submission?" I'm sure that if I underestimated, CGC would somehow inform me and ask for the additional $$ - but what about the case where I may have overestimated? Does CGC inform me and send a refund to my credit card? In the case of multiple submissions/differences in values, do the estimations get summarized and applied to the single order number? That would make sense, but since I have no history of submissions, I just don't know how it works. Thanks for your reply.
