Hello, I have a couple questions abput specimine stamps. The first I think I can answer but will ask it anyway. Can they be used for postage? Are specimine stamps a separate category? In the case of this pair of stamps, I think this issue was listed as 396a-396e. I did not find 396a-396e in the catalog unless I just missed them. Would 396a-396e be the specimen stamps?
Your answers will be most appreciated.
