Can't be of much definitive help with your questions. When I put together my set the cards were typically under a hundred dollars apiece. I saw that an entire set sold for $600 in a Hunts auction but that was 2002. Worthpoint indicated an eBay sale record for the "Safe" card but I do not have access to that site to obtain either the date or price. Perhaps someone here has an account and can get the info.

None of my cards are graded and VCP didn't show a single transaction for PC778 which suggests that they are generally raw. Whether a grading company would mention Collins on the flip or just call it "Safe" would depend on how flexible they were willing to be. The fact that the player is Collins is ironclad so a case could be made to name him.
