Is there a market for 4 cent statue of liberty postcard?

Yes. Statue of Liberty postcards with a 4-cent stamp were issued by the U.S. Post Office from 1885 to 1898. These cards were part of the first series of postal cards issued by the U.S. government, and are highly collectible today. On average, they can sell anywhere from $100 to $1000, depending on condition and rarity. If the postcard is in good condition, and especially if it has the original stamp, it could be worth even more.
