What does "ALTERED" mean?

If the card had been rebacked, it would have expected "Evidence of restoration".

<< <i>it could mean rebacked, skinned, recolored, soaked, pressed, stretched, built up, or anything and everything in between. >>
If that were the case wouldn't it have read Altered Stock?
Rebacked or soaked are the only alterations that might make sense, I can't see why anyone would submit a skinned OJ for grading. It does look a little narrow, so could Altered mean trimmed (or would the flip say Evid of trimming in that case)
