I only collect Canada but on a few older pages that were sent to me there were these 2 Gibraltar one penny. I've been hunting my canadian stamps for watermarks that are barely visable and was amazed how crisp and clean the watermarks were on these 2 stamps. As you can see they were a pair at one time as cancel lines up pefect but I am wondering were these watermarks consistant throughout the paper used or are they somewhat of find.
