Need to know if they are authentic or how to check.

Welcome.

I see. Thanks but how can you tell between the years. They look similar to the rare

Try and find the Scott catalogs in your Public Library (if it is open). They are necessary to correctly identify any stamp . Even with a catalog, it is sometimes not easy. Do not trust the internet for correct IDs.

Hi Mastaluk5,
In my opinion you do not need a catalog, everything you need to know on your stamps is available on the Stamp Smarter website.

There are a lot of clueless ebay listings, investment blogs, and other online resources which say or imply that stamps are rare. But in general stamp are as common as rocks with a few rare varieties. But you can safely assume that any stamp you find is a common variety. (This is the same thing you would do if you walked into your back yard and picked up a rock, you would not assume that it was a diamond.) Stamp collecting is a great hobby and has a lot to offer in the way of learning history, other cultures, and art. But windfalls are more common with lotteries than with stamps.
