howard"These are treasures and should be kept in an unaltered state"
Glue residue itself is the alteration unless the manufacturer issued the cards with ugly bits of paper pasted to them. Removing the glue is just removing the alteration. "Real" treasures are handled this way by museums all the time. Paintings are cleaned, heads are reaffixed to statues, shards of pottery are glued back into whole pieces. Michelangelo's David was damaged 450 years ago and Giorgio Vasari saved the arm and it was reattached. Imagine if the Rosetta Stone was found with glue and paper stuck to it...If "purists" back then ojected to its removal we probably still would not be able to decipher hieroglyphics.
Extreme examples, yes, but my point is why hold cards up to a "greater" standard than one of a kind objects of actual historical significance?
