Contact an art advisor to help you find a buyer for your work or see if an auction house like Sotheby’s or Christie’s wants to auction it for you. If they help you sell your collection, they will make money, so it’s in their best interest not to ask any questions. Make an appointment with an auction house to appraise the pieces in your collection. You’ll sign a contract that says you are allowing the auctioneers to sell your collection on consignment, which means if it sells you get paid, and if it doesn’t you get the art returned to you. It will also tell you what sort of fees you will be charged - like insurance, shipping, and the auction house’s cut. You’ll ship the work to the auction house, wait for your collection to be sold, and make it rain.

The indictment says that Sack and Katzen promoted themselves as fine art dealers who were "capable of selling various works of art to be paid for in cash, as a way to launder money earned through illegal drug trafficking. The pair "offered to resell overseas any works of art first sold by them," the indictment says. One of the acts alleged as part of the conspiracy was the purchase of a cash-counting machine to sort out any counterfeit bills from the millions the pair expected to receive, the indictment says. The conspiracy took place in New York, Connecticut and Massachusetts, the U.S. says.

Forgeries may be detected by the methods of examination formulated by Jean Mabillon, in his great work De re diplomatica (1681), for determining the authenticity of a document by the writing and the style of the terminology. These techniques have developed during three centuries into the modern sciences of paleography and diplomatics, by which various scripts and formulas can be assigned to particular ages and localities, and effective comparison can be made between two examples of handwriting purporting to come from the same pen. Thus it is possible to state that a particular document could not have been written at the date that it bears. In dealing with printed texts, analogous methods are employed.
The AML Standards for Art Market Operators (“AML Standards”) are set forth by the Basel Institute on Governance, an independent not-for-profit organization.  Not surprisingly, the AML Standards adopt a “risk based” approach to establishing measures to mitigate money laundering risks, and further note that “[s]mall businesses may not have the resources to address money-laundering risks in the same way that large auction houses or major dealers and galleries will have, and may have a different risk exposure.”  The AML Standards are intended to apply to everone trading in art objects, and intermediaries between buyers and sellers.  They also suggest that service industries supprting the trade in art objects that are already subject to AML laws, like financial institutions, should identify their clients and customers in the art trade “as higher risk as long as there are no internationally applicable standards.”
Portrait of a Woman, attributed to Goya (1746-1828). X-ray images taken of this painting in 1954 revealed a portrait of another woman, circa 1790, beneath the surface. X-ray diffraction analysis revealed the presence of zinc white paint, invented after Goya's death. Further analysis revealed that the surface paint was modern and had been applied so as not to obscure the craquelure of the original. After analysis, the conservators left the work as you see it above, with portions of old and new visible, to illustrate the intricacies of art forgery, and the inherent difficulty of detecting it.

Governments around the world have stepped up their efforts to combat money laundering in recent decades, with regulations that require financial institutions to put systems in place to detect and report suspicious activity. The amount of money involved is substantial: According to a 2018 survey from PwC, global money laundering transactions account for roughly $1 trillion to $2 trillion annually, or some 2% to 5% of global GDP .
Even though De Sole was appointed chairman of Sotheby’s in 2015 and, presumably, is art-savvy, Clarick points out that his being scammed speaks volumes. “To me,” says Clarick, “it says that the works were pretty good-looking and conveys the impeccable reputation that Knoedler and Ann Freedman had. People believed them. You don’t buy a really fancy diamond from Tiffany and have it checked out on 47th Street.”
Prosecution is also possible under state criminal laws, such as prohibitions against criminal fraud, or against the simulation of personal signatures. However, in order to trigger criminal liability under states' laws, the government must prove that the defendant had intent to defraud. The evidentiary burden, as in all criminal prosecutions, is high; proof "beyond a reasonable doubt" is required.[27]
Further, and as noted, other traditional vehicles for laundering money have become less attractive, thereby driving those who need a mechanism to launder large sums into the arms of the art world.  As we repeatedly have blogged, one of the most time-honored and relatively convenient vehicles for laundering — real estate — is under intense scrutiny and now is subject in the U.S. to the Financial Crimes Enforcement Network (“FinCEN”)’s ongoing Geographic Targeting Orders (these require U.S. title insurance companies in many parts of the U.S. to identify the natural persons behind legal entities used in purchases of residential real estate involving $300,000 or more and performed without a bank loan or similar form of external financing).
Sometimes, they give us works that great artists simply didn’t get around to making. If a fake is good enough to fool experts, then it’s good enough to give the rest of us pleasure, even insight. The late Swiss collector Ernst Beyeler called a fake Rothko from Queens a “sublime unknown masterwork” in 2005 and hung it in his namesake museum. Why not think of that picture as the sublime masterwork that Rothko happened not to have got around to? Is it a bad thing if thousands more people in China get to own works by the great modern master Qi Baishi — even if the works they own aren’t actually by him? In some ways, they are by him, in the profound sense that they almost perfectly capture his unique contribution to art. If they didn’t, no one would imagine he’d made them.
A notable forger of the late 20th century was Shaun Greenhalgh, who created several works of art in a variety of styles and, after carefully constructing a credible provenance for each, sold them over the course of roughly two decades with the help of his parents, George and Olive Greenhalgh. One of his notable forgeries was a stoneware sculpture, The Faun, thought to be a rare unglazed ceramic sculpture by Paul Gauguin, another was the Amarna Princess believed to date from 1350 bc.
Glafira Rosales, an obscure Long Island art dealer, her boyfriend, and his brother enlisted Pei-Shen Qian, a Chinese artist in Queens, to paint Abstract Expressionist canvases in the style of such masters as Jackson Pollock, Mark Rothko, Robert Motherwell, and others. The venerable Knoedler gallery, which closed in 2011 as the forgeries came to light, still claims they believed Rosales’s story that the works were part of an undocumented collection sold directly by the artists to an anonymous “Mr. X.”

   Redistribution of the world’s wealth after the Renaissance created an explosive demand for art by a newly educated and prosperous mercantile middle class. Guilds of Master artists and students became virtual factories for art that was produced to fill this demand. The sale of State and Ecclesiastical art collections created new secondary markets in the form of dealers, galleries and auction houses. For the first time in history, art became a commercial commodity.

If the BSA is extended to apply to dealers in art and antinquities, FinCEN can expect a robust notice and comment period for the implementing regulations.  Further, when proposing such regulations, FinCEN might draw upon some existing AML guidelines for the art trade, including those from two not-for-profit groups — one independent, the other supported by industry.  We explore those guidelines in the rest of this post.
Sack discussed transferring the proceeds from the resale to an offshore account, the agent's affidavit says, and the dealers explained that the buyer would see a net loss in funds. When the undercover agent mentioned normally paying "10% to 15%" to launder money, Katzen said the works could easily be sold at a 10% discount, the affidavit says. Katzen said he would move the money very, very slowly, the affidavit says, and told the agent he had a client in Europe who was ready to buy the Modigliani "under these circumstances."

Art fraud, the deliberately false representation of the artist, age, origins, or ownership of a work of art in order to reap financial gain. Forgery of a famous artist’s work is the best-known kind of art fraud, but fraud may also result from the knowing misattribution of the age or origin of a work of art—if, for example, an art dealer were to falsely assert that a statue was from 5th-century-bce Greece or that a vase was from the Chinese Ming dynasty, for the purpose of making a greater profit, because works from those particular regions or time periods are deemed more valuable on the contemporary art market. Art theft for resale is also a form of art fraud.
