Editing Autograph collecting (section)

===Other authenticity issues===

Forgers buy real [[American Revolutionary War]]-era documents and surreptitiously pen a famous patriot's name between other real signatures in a manuscript in hope of deceiving an unsuspecting buyer. Others will use tea or tobacco stains to brown or age their modern missives.

Many autographed items of famous American sports players being sold over the Internet are fakes. Baseball legend [[Babe Ruth]], for instance, has had his signature forged on old baseballs, then rubbed in dirt to make them appear to be from the 1930s.<ref>{{Cite news|url=http://diginole.lib.fsu.edu/islandora/object/fsu:183605/datastream/PDF/view|title=Sporting Materiality: Commodification and Fan Agency in Collections, Memorabilia, Jerseys, and Dirt|last=Andon|first=Stephen Patrick|date=May 11, 2011|access-date=September 18, 2016|via=Florida State University Libraries}}</ref>
