No one buy blind from strangers in ebay but I thought the risk is significantly lower from an established auction house... Without pictures or being at the auction house itself, and as was stated by coinery above, the grading is a little generous, so as i said, why would anyone buy blind. Also if it's your first time buying from ANY auction house, then in theory said auction house is also a stranger, no? There's overgrading in a lot of auction houses, having the ability to grade yourself gives you the choice of where your bid goes, having nothing at all to go by is Russian Roulette of the highest order no matter which auction house it is.
