3c Washington Stamp - Scott # ??

What is the scott # for this stamp? What year was it issued? Any help is appreciated.

This looks like Scott 64, 65, or 66 or a variety of one of them. Value on these could be relatively low or fairly high, depending upon an accurate evaluation of the stamp's color. Maybe someone else with a color gauge can tell.

I can't make out the postmark, but if it's 1867 or later, it could also be 79, 82, 83, 85, or 88. But then besides color it's a matter of determining the grill, a rough patch on the stamp placed there in printing to better absorb the ink when canceled.

Stamps used to be strictly functional and never issued with their value to a potential collector in mind. The more they could be obliterated with a blot of ink so they could not be reused, the better. I think that philosophy is coming back with those self-adhesives and computer style cancellations of late, though for different reasons, mainly technology.

Hi LeAnn,
modern_who has already given you the possible numbers. Looking at this picture, it is hard to tell, but I don't see evidence of a grill on this stamp. You should be able to see the "grill" if the stamp has one. Most grills look like a little rectangular 2D lattice of cones with tiny pinholes at their tops, somewhat like the pattern you see on a meat tenderizer. As modern_who pointed out, the post office had a problem with people washing cancels off of stamps and reusing them. The grills were applied to just break the surface of the paper a bit so that the ink from the cancel could sink into the fibers of the paper.

Since I don't see a grill, I am pretty sure it is a Scott #65, rose, issued in 1861. The #64b rose pink stamps have a subtle difference in color which gives them a slightly pinkish tint. I don't see any of the "pink" pigment on this stamp necessary for it to be #64b. The #64 pink stamps are much easier to distinguish from #65 but are rare. The #66 lake stamps are now considered trial color proofs and their color is more like the #219D lake stamps. So in the absence of a grill, I would say it is a #65.

these are left to right:
#65 rose (a bit faded)
#65 rose red (your stamp)
#64b rose pink
#88 rose with E grill

#65 has four shades listed in the catalog: rose, bright rose, rose red and dull red. I would say yours is rose red. To be a #64b the stamp has to have the slight pinkish tint. I hope you can see the pink on the 3rd stamp from the left. The fourth stamp is an example of a "grill."
