This is a lot of WW stamps used off paper. You will get 1000+ stamps to make sure that you receive a good mix I will add a few extras. There are a few USA stamps but I did not see many. Please see the photos for details. I know nothing about WW stamps. You may receive Used, mint and CTO's stamps. The stamps are packaged by weight. You will receive 2.5 oz of stamps. this is 1000 to 1200 stamps on avrage. Will do my best to keep duplication down but some duplication is expected because the lots are not searched. 500 stamps is about an ounce so there is .5 oz extra to cover any stamps that may be damaged and the weight of the plastic bag also it is to make sure you receive atleast 1000 stamps You will receive extra stamps to make sure you receive a great mix. I'm adding more stamps daily so the mix is growing! Check out my other items!
