Hello ImNewToThis, welcome!

I like your two mis-perforated stamps, the ones with a shifted holes or perforations or perfs, They are eye-catching.
Some call them errors and some varieties and then some others call them EFOs (short for Errors, Freak or Oddities), a catch-all term.
The two first stamp is nice in that it is well centered, the design centered nicely within the whole edges of the stamp, and there are no cuts, rips or tears to see.
Any little mar or paper fault will drop the value downwards for a stamp.
The second stamp is off center somewhat so is valued less than one like it that would be well centered. But it is nice never the less.
I am new to my basic Scott catalogue so will not offer a balue for any of these. I am more used to Canada stamps and others.
Your library would have a Scott US Specialized catalogue, or you could find one on
ebay, or even a used one a few years old. The classic catalogue would value it OK also.
There could be little varieties on either stamp that I would be unaware of and the catalogue would tell you about.
Please stay and show us more of your collection and post in a USA forum on here or Worl or Main if for fioreign or international stamps from other countries. Remember to put the country name in your title so people who know about that area will see it.
