1963 Topps Mickey Mantle

This card is in very good, not graded condition. the creases on the front is from the plastic sleeve the card is in, then it's inside a thick plastic case with screws. old school protection. But this card doesn't have the green ink over the name like regular cards for this year. I've been able to find a few similar examples online but literally 3 only. There's a forum talking about it and they claim that it's a mess up where the ink ran out and these made it out when they should have been destroyed. I searched Mickey Mantle card sun bleached, or faded and I found the forum. there was another well known auction house that had one for auction years ago but I couldn't find the final amount it sold for. so it's a mystery
