Interesting Washington/Franklin Fake Coils

I found these stamps in a larger auction lot with no expectation of finding anything particularly valuable but I did have fun looking through them and finding the following.

Supposed Scott # 445
Supposed Scott # 446
Supposed Scott # 449

Starting with the 445. Perf 10 coil, single line watermark but it only measures 24 mm in height and the lower margin is cut at an angle.



Next up is the 446. Perf 10 coil, single line watermark. This one measures 25 mm in height but the top margin is cut poorly and I think the perfs on the left are questionable.






Finally the 449. This one is rotary press, perf 10, single line watermark, 25 mm high. It has a pencil cancel and a small thin on one corner. looks real but something about it bothers me besides the fact that I found it with these others. Even though it measures fine, is it too short? The perfs on the bottom look wonky too.





I guess I'm testing my critical skills at detecting these problem children. Any comments, advise, discussion, etc. is highly appreciated.

on your last stamp ... 449 is a Type I, your stamps has the extra shading in the ribbons, so must be a type III.

Oops. I should have seen that--It's a 450 and probably legit. Learning every day!
