6¢ Lincoln
(read how to identify your stamp below)

You have the 6¢ Lincoln from the years 1870-1882. It is fairly common To value the stamp you have to first look for a what is called a 'Secret Mark' and look for an embossed pattern, called a grill, on the reverse of the stamp. An example is shown below.

If the stamp has a grill, then click here.

If the stamp has no grill then examine the bottom left corner of the stamp.

On the bottom left corner the four left most lines of the ribbon have thicker shading. Below this text there are two images, one showing the thicker shading and one with normal shading.

If you see the thicker shading in the ribbons, as shown below then click here on the menu to the left. If the stamp has a date cancel and you can see the date is prior to February 3rd, 1879 then click here. All unused stamps belong to the latter period of numbers 182-191.

If you do not see the thicker shading in the ribbon (shown below) then click here.

Lastly look at the lines that border the image. If there are only three lines, as shown below, they you have the 1882 printing by the American Bank Note Company. The value of these can be found by clicking here.
