Here is a concern I have about sending vintage baseball cards off to a dealer to sell for me. Maybe I'm being too suspicious, but this thought keeps nagging at me and causing me to hold onto my cards even though I'd like to sell them.
OK, so let's suppose I decide to bundle up a couple hundred old (1953 and 1954) ungraded baseball cards and send them to a dealer to sell for me. What is to stop the dealer from substituting a lesser quality (lower graded) card for my card and keeping the better quality card for himself to sell? Unless I've got good, clear, quality photos of every single card, there would be no way for me to prove that the dealer switched cards on me. After all, the cards don't have serial numbers on them and it's not a good idea for me to write my name on the card, so what's a person to do? Serious question.
