6 cents
In mint condition a 6 cent stamp is worth 6 cents (maybe less) for common US postage. However, the collecting value can vary considerably, there are a very few, very old stamps that are worth hundreds of dollars. Most however are going to cost a few cents and the sale value will be small.

The American Legion 1969 6 cent stamp is worth what the market will offer for it. There is no set price to pay.
