What if you were to sell your entire collection

[Exhibitman]

If you've got slabs and they're worth over $100 each, REA's marketplace is running a 5% commission deal. You set the price, they list it and do the work, they get 5%. I've sold several three-figure cards with them in the last month and I plan to send them more. It lets me sell at a reasonable price because I keep 95% of the sale price. That's probably the closest to net retail you will get without actually doing the dirty work of retailing.

For raw stuff or less valuable stuff, I'd start right here with the BST threads. You do the work but you set the price and terms and keep 100%.

If you just want to move it, period, for cash, I'd suggest calling one of the reputable dealers who do wholesale buys. If you are willing to consign, you can't go wrong with REA. LOTG and Sterling. I've done buying and selling business with all of them for decades w/o any qualms. Al (LOTG) is on my wife's call list if I drop dead and she wants to liquidate; I have that much confidence in his honesty and integrity that I'd send a non-collector widow to him.
