The Scott #610 And The #613

The stamp on the left is a flat plate printing perf 11 #610

The stamp on the right is a little bit longer is it a #613

To be honest,
The photos just aren't doing the job. Even if it takes a few days, get scans. No scanner? Then find a friend who can make actual hi-resolution scans (300dpi or 600dpi) of the front and back sides. These angled, low resolution photos are pretty much useless.
Also, like your 596 thread, the odds are very, very, very long at having a rare variety - let alone two different ones at the same time.

100% not a 613. No need for a higher resolution scan.

Philazilla, I agree, but the educational process would be a good exercise, since it appears the OP has doubts.

I am not doubting your expert opinion but it is my understanding that there are only two perf 11 types of this stamp both of my stamps are perf 11 and one is longer than the other therefore I am wondering why you say it is 100 5 not a 613 ...are both stamps 610 even though one is clearly longer than the other

I will try to send a scan of the stamps asap

thank you
