I have been trying to figure out the Smarter Stamp site and learned lots but I can't seem to find info on the stamps with the green lines. I'm assuming from what I read these are cat lines and would indicate a Flate? The postage cancel marks on the crimson one really make it hard to see the nose shadow, mouth and hair locks. I'm assuming that would detract from any value if there is any. The 1 cent 1 stamp has a clear double watermark line on the back but I can't find any on the others. Any help would be very much appreciated. Would any of these be worth getting a grader to look at them? Thanks and take care. Pixie
