Most dealers are not going to be interested in buying a single stamp. You might try selling it on an auction site, but the postage cost will be more than the value of the stamp.
I believe you are referring to a 23 cent stamp. That is Scott Number 2181. It has a minimal value and can be purchased for about 20 cents.
Six cents.

Well a 42 cent stamp is worth 42 cents. There is no mark up on stamps. They cost face value.
