Thanks for the information! It's what I figured but trying to understand what we have is difficult.
If you don't mind me asking how can you tell the difference in U294 and U299? Is it the color of the paper? I researched it for quite a while yesterday and haven't come to any real conclusion. The image I uploaded above was faded when I ran it through the image optimizer so I'm uploading a smaller version of the photo to show the a more accurate color of the square.
I really appreciate the help. The boys were very excited thinking we may have something special so I would like to teach them more about the history of the collecting rather than focusing on values. Understanding the printing process is very important and will help them if they really take an interest in it with me.
One thing to note, the book I am making my way through has not been touched since the early 50's. It's like opening a time capsule. Every page tells a story of some sort and I can't believe the older lady let it go. It was her fathers and she said no one in the family ever took an interest in collecting so it just sat in her dresser.
There are so many unused stamps from the late 1800's and early 1900's it crazy. From all over the world as well. The colors are beautiful so I'll have to post a few pictures as I run across pages worth sharing. My favorite is a single page crammed from top to bottom with Unused Christmas stamps from 1931 to 1943. They look like they were just purchases at the post office.
I'll stop rambling but if you have any links that will help me research the difference in cut squares and all stamps I would appreciate it.
Thanks!
