im going to send some autos to psa/dna to get "certified" im going to send some big names such as ripken jr, puckett,sandberg, gwynn, bonds, etc...my question is how safe is it to send cards to psa/dna.what can i do to ensure they are received safely? i ask, because i have never sent them cards before and dont want them to become "lost" and tips or advice? thanks
