Recently I have sold some signature baseball cards. I've noticed that a few of them are going to authenticator
Prior to being sent to the buyer. I assume this is something new or just something I've never encountered yet. I have a good idea what this is and have no issues with someone making sure the card is real. This service seems to slow down the cards progress in the mail to a turtles pace. I also don't understand why a buyer would want a factory certified signature authenticated. Not new to e-bay but a little confused.
