One of the biggest drivers of an items value is its provenance. Provenance is the history of ownership and identity of an object. It can include auction houses, dealers, or galleries that have sold an item, the private or institutional collections in which the item has been held, and exhibitions where the item has been displayed. It can also include academic research and catalogue raisonné inclusion.
