Free shipping auctions will ship in a penny sleeve, top loader, team set bag taped to and wrapped in a sheet of paper before the paper is taped to the envelope. I have yet to have an issue with hundreds if not thousands of cards mailed this way. You can always upgrade to a bubble mailer for $2.99 in which case tracking will also be provided.
I understand. I am a collector as well. I just know that a PWE when done correctly does work for low-end cards like this as well as it would cost me a fortune to ship out hundreds of cards per month on a "free" site like Listia...
