This is a common US commemorative.
If you want to buy just one it will probably cost you from 10 to 25 cents at a stamp store for a copy, mint or used.
Dealers get them as part of larger lots for almost nothing per stamp- say 10 cents if mint and 1/2 cent if used. The money they would charge you for it is mostly for labor.
I think it is a nice stamp and I would certainly keep a nice copy for my collection.
