Maybe. The one I have carded witha hole is dated 80502. You can definitely see the hole from outside the package without opening it. I used a led keychain flashlight (a really bright one) to shine down the top of the figure and look behind him. The fact that the cards have that foil backing helps it reflect a lot. If you can't see a hold doing that, then it isn't there.
Some figures (like Stalker) are tough to see because they have a strap in the way. But SS's quiver isn't a problem. If you look at a TRU Red Ninja or any of the more recent SS figures that have the hole, you can see what wrinkle the hole is near and can narrow it down from there.
It made finding SS without opening one possible, but I looked in a bunch of Stalkers by opening them and now I have loose extras.
