Would like another set of eyes to check this please
This first photo is what I shipped. You can tell the material around the coin is felt as there are various bits stuck to it. The second photo is when the buyer is claiming I sent him. The material around that coin is not felt, if you zoom in. He is claiming I sent the wrong coin but would accept it if I sent him some money to “cover the difference”.
I think I am going to fight this. I am not a coin guy this was a gift a long time ago. From a neutrals point of view, am I in the right?
