I have a T206 SHAPPE that is not labeled as such, and my theory is that it was graded before the "error" was recognized.
I didn't see a date listed when using PSA's online cert verification, so I called in, and much to my surprise, they said that they "don't do dating on em'".
Is there any way that you know of to find an approximate date?
I suppose it's also possible that the person submitting the card was clueless and didn't specify on the form...
