There are two types of surcharge on 118 and 120. Type 1 has the denomination underneath the bottom grape at the lower left corner of the stamp. Type 2 is a completely different setting with the denomination at the lower right of the stamp. Type 2 is found just once per sheet on certain sheets of 100. Relatively scarce and overlooked by most (until now!).
