The first thing you should do when selling an old painting is to make a list of the previous owners. Then, you can ask the seller where they got it. If you don't have this information, you should look up the painting's history in the internet. This will give you a better idea of who has owned the painting. It's important to remember that the older the painting is, the more it will probably cost you to sell it.
Another way to find out if a painting is worth its price is to check its back. The back of the frame can tell you a lot about the painting. Older frames usually show signs of age. Authentic art is usually in an older frame. The back of an old frame typically has an X or H shape. Contemporary frames don't have these features. So, if you want to sell an old painting, pay close attention to the details.
One of the best ways to determine the value of an old painting is to find out who owns it. If it's a high-profile person who has been in the art world for a long time, its value may have increased. If the painting was created by a major artist, the painter might have known its value and sold it for a high price. In addition, the original art is the first authentic representation of a piece by an artist. This excludes subsequent prints, reproductions, or imitations.
