Crack! It has that PRO feel to it in that holder based on the below examples. Not all of your, or your family's, potential buyers will know the history of card authentication and will be hesitant. An SGC 10 or authentic will be great for that fantastic card.
I have mentioned in a recent previous thread that I like the ASA holder as a nostalgic sort of piece, so I also understand where Peter is coming from.
