I've found the best way is to do what is typically done; two pieces of cardboard around the graded card and put into a bubble mailer...but then put that bubble mailer inside the small priority mail box(the one the size of a VHS tape).

Then put that small priority box within a full sized rectangle priority box and cushion it with bubble wrap or peanuts of your preference.

This gives max protection, and with it being inside the larger priority box it doesn't look like a baseball card is being shipped. Also, the larger box is a little harder for someone with sticky fingers to slip into their pocket or bag.

The process does not take long at all, and the boxes are all free from USPS.

Stealth and protection.
