Brandon also works VERY close with ebay's fraud division on a daily basis. With Brandon's help, HUNDREDS of NASCAR forgeries have been removed from the marketplace each year.

Brandon's goal in the hobby is to simply help educate the buyers and to remove as many forgeries as possible within the marketplace. Brandon continuously render's his opinion for to ANY customer who seeks his assistance he enjoy's the personal contact with customers which allows him to ensure that the customer has a clear understanding of the item in question. Brandon has time and again shown that authentication should be less about making money and more about educating buyers in hopes that they will not be a victim of a forgery.

Brandon's current opinion is that NASCAR autograph forgeries are on the rise faster than ANY other section of the hobby. This is mirrored by NASCAR's international growth and continuous gaining of popularity. The huge DEMAND of NASCAR driver's autographs can not meet up with the supply. Though it may be that EVERY NASCAR driver signs HUNDREDS of autographs a week during the race season, the supply can not be met in the market due to the high number of COLLECTOR'S who keep the autographs out of the commercial system.
