You can also use a company name JSA to authenticated them. One of my buyers only purchases PSA/DNA but my others respect JSA opinions. If you need more info on how to do it PM me. You maybe able to get JSA to give you a break on the fee's PSA/DNA not a chance on fee break. Just so you don't go in shock the authenticity fees will be about $75 to $150 per item. Don't worry about that because you should be able to make that up when you sell them.
