Help In Identifying 1920 Washington

Any help would be greatly appreciated... Thanks in advance...

What make you think it's a 1920?

Check for watermark. Single line watermark it's a 1912 Scott #409. No watermark it's a 1916 Scott #482.

Hey thanks for the reply... Well 1920, was an part of the initial thread I had responded to in which the stamp was a 1920, I should have fixed that when I reposted here... I do not see a watermark, and the Schermack perforations at right had me leaning to the 1916 482... But which one..? The 482A is insanely rare apparently, especially unused... How would one tell the difference..? or further identify the 482..? I'm fairly new into the stamp world so please bear with me... Thanks a million and I look forward to learning more...

482 type 1, Definitely not 482A because of toga line weakness.
