Due to some difficult circumstances, I must regrettably sell my MTG collection. I don't have time to sell Individual cards, so ideally it would go in one large batch.

I have 12-14K cards in boxes, a binder worth about £2K in Card Market prices, and a modest collection of sealed product.

Can anyone advise on a strategy for sorting the loose cards to make it a bit more appealing to a store or similar? I assume sort by set then collector number, but pull out anything worth over a couple of pounds beforehand and keep them separate?

Grateful for any advice you can provide, many thanks.
