I think they may be the only examples! With these, its the very solid provenance, which is described in detail in Lelands' write ups, I imagine the relied on.
I have no personal idea the circumstances in which SGC (or PSA) will or will not authenticate something. However, in conversations with a few AH owners who have sent things to TPGs to be authenticated, TPGs are very hesitant to slab something as authentic unless they are totally confident they know what it is and in its authenticity. What could make a TPG confident? Prior examples, provenance, influence..... (at least these are what I could come up with).
