Are plate-signed lithographs worth anything?

Yes, some plate-signed lithographs are worth something. With a plate-signed print, the artist paints or draws their signature onto a stone along with the image so they are printed together. Generally, plate-signed prints are worth more than unsigned prints, but not as much as ones that bear handwritten signatures. When valuing a print, experts consider the artist, age, historical significance, image quality and overall condition, in addition to the type of signature. A certified appraiser or knowledgeable art dealer can evaluate your lithograph and give you an estimated fair market value. Find a wide variety of lithographs on 1stDibs.
