Type 1 And Type 3 Vs Type 4

Hello everyone. I've taken the advice and am using Stamp Starter to educate me. I've been going through a bunch of '84-'85 Washington's and I want to see how I am doing in my identification.

The first I'm gathering they are Type I because of the lines are clear and go through the triangle.



The second is a Type 3 because of the way the right side of the 'T' is curved


And the third is a Type 4 because of the 'T' is sharp angle.




Am I on the right track?

Thanks so much

Not quite, Type A, B and C are all different background lines and the way they cross ((or don't) the triangles. Type IV has other differences, one of which is the straight at the right side of T of Two.
I couldn't get to open details on the stamps smarter pages, so I took a few pics to help.

Thank you very much for your reply. I'm learning so much from this community.
