Your listing perhaps could have mentioned that these were 25 cent tokens, because sometimes when you deal with eBayers ,you almost have to pry their eyes open with toothpicks and have audio as well as video clips on your auctions, so that they actually understand what you are selling, BUT...your pictures are as clear as day.The buyer could have contacted you before the feedback but chose not to, and because of that....he deserves nothing.
And you did respond to his feedback properly so that others wil see that you handled it well.
Next time though....video and audio clips
