As Greg pointed out they are the same size & thickness as a real T3, and via a scan & to the untrained collector can be easily fooled.
I wish they would have dated them 2007 (or whenever they were made) or but a bold "REPRINT" on the back.
Only the starburst in the bottom 2 corners as Greg stated differentiate them from the originals.
Also the real ones have a different finish, like an oil painting gloss.
Here's is the Mike Wheat one on top and a real T3 on the bottom without the "starbursts"
