History

James Spence Authentication, LLC was founded in Orwigsburg, Pennsylvania - May 2005 by world renowned autograph authenticator, James Spence, Jr. For over 30 years, Spence has built a reputation second to none in the autograph industry. After several years of JSA's growing demand, the autograph authentication service needed to shift it's operation to Parsippany, NJ for better access to the NY/NJ market. Employed by every major auction house in the country, JSA has accumulated a massive exemplar database totaling nearly 500,000 files. This extensive exemplar library is imperative for JSA autograph authenticators to utilize when accurately assessing the thousands of autographs submitted daily. JSA opened it's first expansion office on August 31st 2012 in Fort Lauderdale, FL.
