Show Your US 1847 Issue Stamps & Covers

1847CensusTaker, I have a copy of the left pane sheet and a copy of the Perry Plates that I got from William Crowe. The trifoil image would not help with the above stamp since it has no guide dot in the first column of both sheets. I have been adding right pane images recently to the right pane. I still have more plated images to add. take a look at the recent additions.

Jaxom100, good point about the lack of guide dots for the 1st column. That's why the horizontal position of lower right corner of the partial image of the stamp above the one on cover is helpful. With very precise measurements, the correct plate position could probably be determined.

jaxom - I will see if I can get a better image.

Mark S - great work on the cover census, that is a very valuable resource that I and others use a lot.

Do you have any current thoughts on the likely number of remaining 1847 covers out there and what percentage coverage you might have? I know these numbers are hard to estimate, but in some instances its doable depending on what we know about survival percentages...vs total printed, etc...
