How much is a penny black stamp worth?
If you are referring to Great Britain’s first stamp issued in 1840, then the value of your “penny black” in Very Fine condition would be $275. in used condition and $6,000. in unused condition. Of course that would be the price you could expect to pay a stamp dealer, and if it is in a poorer condition than Very Fine, that will bring the value down. On the open market you probably can get $125 US for used and $2,500 US unused. In Pounds that would be about 55 and 1095 respectively. If you are in Great Britain, then you could look it up in your country’s most prominent catalogue, Stanley Gibbons.
