This is a two cent red brown stamp with a bust of Washington, side view on it. There is a green stamp that looks just like it, except the color.
Firstly, the stamp is NOT from 1732, as that was the year Washington was born. Some people ask the moon for one, but a used specimen is only worth a few dollars.
George Washington and Benjamin Franklin were the first two individuals. Washington was honored as the first President. Franklin was honored for being the first Postmaster of the United States.
The first US 3-cent stamp was issued July 1, 1851. It contained a profile of George Washington in a rather ornate frame and was red-brown in color.
The value of one Anna red stamp is 20 cents. It is much higher on Ebay.
The US has issued many dozens of red 3 cent stamps. It will take a bit of work to identify which stamp you are referring to. I would recommend spending some time looking at a US Postage Stamp Catalog to identify the specific stamp. The bonus is that most catalogs will give you an idea of value.
These came out May 10, 1971. One is claret , the other black with red lettering.
Red or Red-Brown one cent coins do sometimes have premiums, but it depends on the type, date and mintmarks of the coins. No set value exist just because a coin is Red.
