On the first of the year, AB-1570 Collectibles: Sale of Autographed Memorabilia went into effect in the state of California, requiring all dealers of any autographed material worth more than five dollars to fill out a certificate of authenticity (COA) specifying date of sale, the dealer’s name and street address, and the name and address of the person from whom the autographed item was acquired if the item was not signed in the presence of a dealer. While AB 1570’s goals are to prevent the distribution of forged autographs, many booksellers feel they’ve been swept up by a vague law with onerous requirements and that portions constitute an invasion of privacy, citing possible violations of California’s Reader Privacy Act of 2011.
