For no reason the issues from the early 1920’s are hard to find used on cover. The most difficult to find on cover is Scott 111J which consist in an overprint for coffee promotion that reads “COMPRE UD. CAFE DE COSTA RICA”. There are only 13 covers known with that stamp.
Scott 111J has an error (position 72): instead of “UD” it reads “VD”. Some people say it was made on purpose some say that it’s a legit error -that will be addressed in another post-.
So, what are the chances that if only 13 covers are known, one of them has the stamp with this error? Low, very low.
The nice thing about the mentioned cover is that it doesn’t have 1 stamp, it has a block of 4! and if that wasn’t amazing enough, it also has the 20 Cts from the Jesus Jimenez issue!
