For what it's worth, the, "Buy the card, not the holder," mantra does serve one very well on resale as well. Time and again I paid premiums for lower grade cards with great eye appeal that some thought were crazy at the time, only to do very well on those occasions when I sold some of those very pieces to go after a pricier card. There are many ways to be happy as both a collector and seller, for us all
I'd add that if one intends to hold a card for a long time, or as I've heard some say a long "investment horizon," one can feel free to pay more for a 4 that looks better to their own personal eye than a 5 which would have cost them less, since they can always hold their preferred 4 long enough and enjoy it during that time. Bottom line, I think so much of collectors' discussions hinges on where the discussion participants each fall on the collector versus investor spectrum.
That said, were I in the market for that 4, I would set my bid, and if it turned out to be higher than the 5 sold for, I would not care at all-- I took home the one I wanted at the price I wanted to pay, is all that matters. I have done it before (with many cards in my collection, and some well north of the price mark you referenced) and— if I love a card— I will definitely do it again,
When I love a card, there really is no helping me, LOL!
