I found some toploaders that would work but they want $20 for 3! Link below.
These are the same as the 25 pack of 6"x8" BCW top loaders for photos but come with and inner sleeve. I want to send my wheaties cards into get graded and do not trust just the 6"x8" toploaders without inner sleeves. I also do not really want to pay for a full box of 25... Here are my cards...
