Hi there!
I joined this forum to get more information in regards to finding the difference between similar looking stamps (Ex. Scott 179 & 185). From a post I read in this forum it helped me separate 3 179's out of my stash of 185's (30+). Similarly I have quite a few US Washington 2c types (1917ish?) that I need to separate out (1000+).
My collection includes issues from 1870's to 1940's from mostly the US and Greece. Next to those, I have similar date ranges from the British Commonwealth / England, Netherlands, Belgium, Germany and the Ottoman Empire / Turkey.
This new year it is my goal to organize!

Cheers!
