I bought a used Red Monkey stamp online, so I'm not sure if it's genuine. The Liaodong Peninsula Liberation Commemoration Sheet has a diagonal line on the face value, so it's a replica. Most of the Mongolian stamps are used and have postmarks. I have many stamps from the Southern Occupation, animals, dinosaurs, insects, and marine creatures. If you are interested, please comment on which country or region you prefer and what kind of designs you like.
