Does the angle used to photograph coins for sale help hide defects? I see lots of coins for sale that are not photographed straight on. I suspect that taking a picture at an angle makes a coin look better. As an example, look at the following:

Slight angles can make huge differences in how bagmarks show. On occassion, a forum member will post several pics of the same coin and at first glance it appears that each is a different coin.
It's basically impossible to grade a coin based solely on a scan. If a seller doesn't have a return policy, especially for a raw coin, run the other direction.

Now, you can't grade a coin by the photo, but you can get an idea of what it looks like.
(I have never purchased from the seller, and I don't know the seller, but they look honest.)
