Hi,
I think the problem is that value and worth for any deck, more so modern deck, can vary a lot. If you're looking to sell something quick or soon, then take your best offer. If you wait for the long game, the deck could potentially go up in value or sink in value for whatever reason. And ultimately value/worth is what someone else is willing to pay for it. You can believe it's got a high value but if you can't find someone to give you that value for it, then it's really worth less.
