....."but generally, the coin will be returned with the same grade, and the seller is out the price of resubmitting the coin. He said it was the exception, not the rule."

"Generally" the broken-out, formerly slabbed, now 'raw-coin' being re-submitted for a new grade, is more than likely done by a knowledgeable coin dealer who disagrees with the grade that was originally assigned by the "independent 3rd-party grading service".

There are coin dealers who go around to tables at every major coin show looking to pick out slabbed coins for sale at low prices that they feel have been UNDERGRADED by the grading services. After the coin show is over... the bourse floor is usually littered behind vacated dealer tables with busted-up, cracked-out, case remnants that USED TO house slabbed coins. They then break out the coin and re-submit it to the same grading service ... or a different one ... in the hopes of it coming back at a higher grade than the original grade assigned. It's almost like doubling down in gambling. Sometimes you win ... sometimes you lose. A difference of ONE POINT between the original grade and the re-submitted grade on the same returned coin provides for a good living for those coin dealers who know what they are doing playing this numbers game.

A chip collector who knows what he/she is doing ... does not need 3rd party professional graders. As Aaron Peacock so eloquently posted ... there are not that many super chips available compared to thousands of valuable coins that will probably eventually drive out the lower end grade/condition/value chippers.

In addition, many of the more valuable chips offered for sale have a well-known track record of who owned the chip before it was re-sold to the new owner. That historical provenence alone is probably worth more than a slabbed chip with no such record..
