Welcome.
From your question I infer you do not have a catalog. You will likely eventually want a Scotts Specialized to help with identification and with judging relative value. In ordinary times, you could likely borrow one from a public library, but many of them are closed now.
There are a variety of online tools available as well, some of which are easier to use than Scotts.
You might find

You will want a perforation gauge (there is a printable one at Stamp Smarter) and eventually you would need to get into watermark detection. Plenty of threads here on the Forum about that when the time comes.
Enjoy the puzzle!
