prewarsportsI feel that the market price for the following three authenticators/companies is essentially the same in the current market.
PSA/DNA
Jimmy Spence
and possibly
Mike Guttierez
However, their prices to authenticate might fluctuate so you might be able to maximize your profit based on what each comapny would charge rather than what the pieces would bring on the open market based on the COA. If you had any of these people authenticate your item for resale on ebay or in an auction, you would come out about the same in my opinion.
