It bothers me to get these cards in "damaged" condition from trades and ebay, because the the whole point of the issue is that the cards are uncirculated (untouched). Once the case is opened and the seal is boken, they are effectively circulated, whether or not you actually touched them. For those of you picky about condition, these would be considered a lesser grade, believe it or not.
Protecting the case from the beginning is the answer or suffer the occassional consequences trying to trade them for top dollar to purists. However, many people don't preserve the cases and once damaged, I'd take them w/ the card out, but would prefer to do it myself rather than get it that way.
