JoannI don't know if the creases reappear over time or not, and to me that is the cornerstone of the answer.
If no, then the card is fixed for all time, then I don't think it's an alteration.
If yes, then the crease was removed with the intent of improving appearance temporarily - long enough to deceive a buyer and raise the price.
Somehow, to me the whole issue of alteration has an element of deception to it for purpose of increasing value. If it would permanently improve appearance as if it were never there, no problem. If it is intended to deceive any future buyer, then problem.
Don't know where crease removal falls b/c I don't know if it is permanent or not.
