I'll throw a few of my favorites in there. I'd suspect all of being unique or one of a kind errors/printing goofs although I don't think any really fall into the "scrap" category.
The M116 Mitchell is a black and white variation and I only am aware of one other m116 like this in existance. The e95 Cicotte should be fire-engine red but is instead neon orange. The e94 Doolan represents not only the only silver e94 Doolan, but the only silver e94 period that I'm aware of in existance. And honestly, I have no clue what that McGraw card even is! It's got the feel of a handcut caramel card of some sort and the pose is the same used on his e94. That's about all I know on that one
