Questions About Unknown Engagement Rings
  • 1stDibs ExpertSeptember 9, 2024
    Yes, paintings by unknown artists may be worth something in some cases. When a painting’s maker isn't a well-known artist or is completely anonymous, factors like the visual appeal, historical significance, previous ownership and condition will determine the value of a painting. A certified appraiser or experienced art dealer can evaluate your piece using these criteria and provide you with an estimated value for your art. Shop a wide range of paintings on 1stDibs.
