But, just as a company's growth can boost the value of its shares, what sort of things should you look for as an autograph investor? Well, a good place to start is landmark anniversaries...
Take today (June 22), for instance: the landmark 100th Anniversary of the day that Britain's King George V was crowned at Westminster Abbey. Royal autographs are among the best autograph investments - after all, these people helped change history.
Historically, big anniversaries have encouraged collectors to want to buy the person in question's memorabilia. This was shown during John Lennon's landmark 70th birthday, last year...
He wasn't a Royal or a politician, yet the former Beatle's impact on culture as half of the 20th century's most important songwriting partnership is beyond dispute. His signed album pages went up in value by 5.04% (that's on average £5,950 up to £6,250) over the past year.
A jacket Lennon wore in a 1966 Life magazine photo shoot was sold for $240,000 in December by Julien's Auctions And an original copy of his handwritten lyrics to "A Day in The Life" sold for $1.2 million at a Sotheby's New York auction in June
