I saw this being discussed on the Blowout forums but wanted to get the discussion going here.
Ebay appears to be offering a trading card authentication service for any card with a value of $750. Doesn't look like they actually grade it, just confirm it's authentic.
It appears the seller ships the card to eBay, they authenticate it, and then they ship it to the buyer.
Ineresting.
