To arrive at a specific monetary value involves research collecting data from multiple sources including:

• Museums and commercial galleries purchases & sales
• Art dealers sales
• Curators opinions
• National Galleries purchases
• Auction houses record prices
• Experienced art consultants
• Corporate collectors purchases and sales
• World art market purchases activities

Artwork value is created by reputation of the seller and history play the essential role of supplying attribution, establishing opinion and authenticating works of art offered on the World Art market.

These elements may affect an artwork value

• Is the item you own, a museum-quality work of art?
• Is the artwork scarce or otherwise?
• Is the artwork historically important, it is illustrated / publicized?
• Has it an influence or has it been influenced?
• It is the artwork representative of the artist?
• Is the artwork from the period of the artist high-acclaim?

Artwork value may be affected by

• the artistic (and or esthetic) merit
• the quality and the rarity
• the provenance
• the style, title, subject and the condition
• the artwork size may not necessary qualify its price or affects its value
• the nature of attribution including a scholar's opinion, as well as which scholar attributions

Art valuation is the process of estimating the potential market value of a work of art as a financial valuation, apart from an aesthetic opinion, subjective views of cultural value play a part as well.

The basic level of price determination, provides an estimate of the current market value of a work of art, is to look through the eyes of an art-speculator without taking into account the true value of a work of art existence for the pleasure its gives.

The Research and investigation of a work of art has a particular importance, firstly, to authenticate the artwork and secondary, to value the object.

Art appraisals to a great extent, depend on the advice and enthusiasm of a variety of specialized market analysts, curators, museums and commercial galleries.

Artwork value is enhanced by competition for the work, rarity as well as the current trend, taste, publicity, beliefs and style.

The art market's participants and other limitations dictate the size of the market and increase the risk that some items may be over or undervalued.

Comparative techniques are, seeing the objects at hand, expert opinions, investigation, study and the results of tests may also be used, but establishing provenance is essential.

The purpose of tracing the provenance of an object or entity is to provide contextual and circumstantial evidence for its authenticity, the original production or discovery, by establishing, its history, especially the sequences of its formal ownership, custody, and/or places of storage.

The World art market operates in an economic model that considers more than supply & demand, appraisals require continual research, works of art are not fungible like stocks.

It is a hybrid type of prediction market where artworks are bought and sold for values based not only on a work's perceived cultural value, but on both, its past monetary value as well as its predicted future value.

Unlike the volumes in the securities market where millions of people and firms participate in buying and selling financial interests, or the commodities market where measures of raw or primary products are exchanged using standardized contracts, art market activity largely follows the demands of a more limited array of private art collectors, museums, and large corporate interests as the principal market participants.
