Editing Autograph collecting (section)

===Authentication===
With the recent enormous growth of autograph sellers on eBay, and the appearance of a multitude of new galleries and retailers offering expensive autographs, casual autograph collectors and one-time buyers have in many instances sought certificates of authenticity issued by the seller at the time of sale. As with any guarantee, these certificates are only as dependable as the seller issuing them, and if the seller is a fraud, then the certificate, and the possibility that the signed item could be considered worthless. Any certificate or similar issued by a seller should always include the seller's full contact details and any details of Association memberships, and these should always be double checked on the Associations website.

In many instances, sellers will use a professional authenticator to determine the authenticity of the material they wish to bring to market. The autograph industry is currently contentiously split between two types of authenticators: those who rely upon their professional expertise and experience personally having collected or sold large inventories of autographs over a period of many years, such as the consultants at AutographCOA.com (ACOA), and "forensic examiners" who rely on academic credentials. Disputes have led to court actions, most notably gallery owner American Royal Arts vs. Beatles autograph dealer Frank Caiazzo, often used by autograph sources such as [[RR Auction]].

Potential autograph buyers uncertain of the legitimacy of the seller or authenticator may research both parties, and may check any dealer who claims membership of any association. PADA, the UACC, RACC, and AFTAL include a list of dealers on their websites. This research should not be limited to a seller's or an authenticator's website which could be prejudiced. Some dealers have been known to invent their own association, e.g. "The Universal Manuscript Society", to enhance their reputations.

Mastro Auctions, a major sports autograph auction house which used a professional authenticator, was sued by a dealer in 2006 (''Bill Daniels v. Mastro Auctions'', Boone County, Indiana, case #06D01-0502 -PL- 0060). Daniels said that he had bought more than 2,000 signed photographs of athletes from Mastro and claimed that the catalog incorrectly described them as all being in color and 8" x 10" in size. Daniels also claimed that some of the autographs on the photographs may have been fakes. He produced two dealers who he said were autograph experts, but Superior Court Judge Matthew C. Kincaid excluded their testimony saying that neither Steve Koschal nor Richard Simon "possess sufficient skill, knowledge or experience in the fields in which they were asked to render opinions." The law for each state is different regarding qualifications to testify. Simon and Koschal have both testified in states where their testimony is accepted in court.<ref>{{cite news |url=http://www.nydailynews.com/sports/more_sports/2007/07/15/2007-07-15_lack_of_intent_seen_in_flubs_at_auctions.html |title=Lack of intent seen in flubs at auctions |newspaper=NY Daily News |date=July 15, 2007 |access-date=January 10, 2012}}</ref>
