ID Of Some 19th Century US Stamps

Hello, I have finally decided to tackle a small packet of 19th Century stamps I had set aside. I did this mostly because it is intimidating! I have tried to go through as best I can and ID these stamps, but I still have a few questions regarding why a stamp is and isn't a certain variety. Some of these are a little damaged, but I want to get the process for ID'ing correct.



The first stamps are these 2 cent brown Washingtons. I measured them at perf 12 and they have no watermark. They are probably all Scott 210. My question is the middle stamp looks to be a different shade of brown. There is probably no chance it is a 211B pale red brown, but I can't find a good picture online of the stamp. What eliminates this stamp from 211B consideration and is there something else I should be looking at for ID'ing purposes.




My next question involves this little beauty. I have measured it at perf 12 and it has a double line watermark. Based on the design it is either a Type III, Scott 267, or Type IV, Scott 279B due to the fact the horizontal lines do not go between the triangles. I have it classified as the Type III, but I am not fully confident in eliminating in from Type IV consideration. Unfortunately the cancel is pretty heavy and obscures a lot of the ID potential of the Washington engraving. Also, the color looks a real light red, almost pink, and I am not sure if that has any factor into the identification of the stamp.

Thanks in advance for any help! This is making my brain hurt on a Friday night. I just cracked a beer in order to try to get through this stuff.

I would say the first three stamps are all 210s. The Scott Specialized Catalog notes various colors including red brown, dark red brown and orange brown, with no change in value for each variety.

The second stamp I wouldn't want to comment on without seeing a larger, higher resolution example, since the key is in the stamp details.

WT,

Thanks for the help. After stumbling upon this old SC thread (derp!), it does appear that they are all 210's as there are a variety of color shades. https://goscf.com/t/36865

I apologize for the photo of the second stamp. From some further research, it appears to be a Type III based upon the smooth oval.

The web site www.1847usa.com is an excellent reference with detailed images of the various US types and detailed images of each area where type differences can be seen.

Minimum resolution for typing a stamp would be 600 DPI on the scanner assuming the .jpg is saved at a reasonable resolution. An optimizer can produce a clean sharp image without requiring a huge file.
