This is the first example of a Cuba #E5 Spec. Del. Stamp that I've seen with top border imperforated. Per the Scott Catalogue listing, the stamp "exists imperforate" at a much higher valuation than the perforated issue. Is this stamp somewhere in between; thus a coil, or booklet issue? If so, is the valuation greater than the catalogue listing for a fully perforated stamp?
It is a straight edge from a pane of stamps. Along the top you can see the cut line where the pane was cut from the sheet. Straight edges lower the value.
