3 cent
1856 3 cent coin value
This is a common US definitive, but not the most common. 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. If you want to order it by mail, you would have to pay postage and handling in addition. Dealers get them as part of larger lots for almost nothing per stamp- 80% face and 1/4 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. If you more than one, maybe you can trade it for another similar stamp . In a trade I would as ask for a commemorative or 2 or 3 more common definitives.

Not sure what you define as an original stamp. A US 3 cent unused stamp is worth 3 cents toward postage. It may have more value as a collectible, but you would have to consult a stamp catalog to fully identify it and get an estimated value. You might try the online version at Mystic Stamps as a starting point.
