I Highly recommend 4 Sharp Corners. I have sold a lot of cards & comics from $10-$5,000+ with them. The payments are always right on time (or early) and the rates they offer beat what I would pay using my eBay account. The emails with expected payments are timely and accurate. I have used multiple times to consign and every experience has been excellent.

I bought a PSA 10 card that was clearly damaged during shipment. They told me they do not accept returns. So I’m stuck with a worthless card. I will never buy from them again. Buy from them at your own peril.
