I have this mint stamp from Bolivia (Scott 438) that is missing the overprint that Scott says its suppose to have. There is a stamp from the same series at the top with its correct overprint (Scott 436). According to Scott, the stamp missing its overprint should be overprinted with 400bs. Is this an error? Has anyone ever seen this before?
Correct, with overprint
Incorrect, missing overprint*** Moved by Staff to a more appropriate forum. ***
