How much are oil paintings worth?

Any artwork is worth and only worth the price someone is willing to pay for it (unfortunately, whether one can afford it or not is another story). Different people may have different reasons to attribute value to an artwork, from the purest (falling in love with it) to what is often considered as the most vile (speculation), going through remembrance, pride of ownership, or brag, among other reasons. For most living artists, the price of the artworks is usually set by the artist and/or the gallery which represent him or her, by type and size of artwork, and corresponds to an equilibrium price between the rate at which artworks are sold and the rate at which new artworks are produced by the artist. For artworks from dead artists sold by professional dealers, the price is often based on auctions results for similar pieces of the same artists. Oil paintings are usually pricier than other techniques because it is considered more difficult to master, but also because oil paintings are known for their ability to last centuries.
