What are 29 cent Elvis Presley stamps worth?

US Scott Numbers 2721, 2724, and 2731.

This is a US commemorative stamp but there are three versions of the Elvis stamp and one is slightly less common than the other 2. The stamps themselves in used condition are available for about 20 cents. An unused or mint it would be 60 to 70 cents. If you want to order it by mail, you would also have to pay postage and handling.

Dealers get them as part of larger lots for almost nothing per stamp- say 65% face if mint and 1/2 to 1 cent if used. The money they would charge you for it is mostly for labor.
