I,m still awaiting a response for the 1906 shilling which i purchased from ebay last week. I listed a pic on the forum about it. Like you it was a poor quality coin i received. Looks like i will have to open a case against him.
Did the old boy not have the coin he had pictured? Yes, he is always open to a haggle. He has a site on ebay, cott2556, you will see what i mean about his pictures, although at the moment they look not too bad.
Here's one i purchased from him last night.
