I am a true collector.....I enjoy the cards like your wife does....I love to smell them, stare at them, find examples....
I appreciate the fact that she enjoys them for their true beauty, as I do...
I can appreciate where she's coming from....
my true suggestion, is have her enjoy them.....then, when it's time, pass them on to your kids, or like you said auction them off....but, JUST ENJOY THEM!
condition, for me, is really not an issue when it comes to collecting my cards....
actually, the uglier , the better
