Grading pottery is difficult, even under ideal conditions. Often condition issues are overlooked for important pieces. It is always best to be overly critical of a piece's condition when selling it. Astute buyers will recognize this right away, and gain a level of confidence with the seller. Show any problem areas when possible. If you are unsure of how to rate a piece, post it to the Discussion area, and ask for help. Of couse you must provide good photos and detailed discription.
