Abraham Lincoln is also the most highly collected President in America, surpassing even George Washington in terms of collectibility, and the overall field of Abraham Lincoln collectibles is often referred to as "Lincolniana".

Joseph P. Leithmann Jr. (1939-2005) also felt that Abraham Lincoln was America's greatest American President. So much so that he spent more than 20 years of his life collecting Lincoln Memorabilia. Joe Leithmann first started collecting Lincolniana on a part-time basis while working at Philadelphia Electric. Joe truly felt that Lincoln was a great and honest man and began seeking out anything related to Abraham Lincoln. After his retirement in 1991, Joe spent the next 15 years pursuing his passion on a full time basis. Not only did he collect Abraham Lincoln Memorabilia, he collected anything even remotely related to Lincoln…Lincoln Highway…Lincoln Savings & Loan…Lincoln Logs. Joe even drove a Lincoln Town Car. He purchased single items, and he sought out entire collections. He would even purchase entire boxes of items at Auction, just to acquire one single Lincoln item within that box. If it pertained to Abraham Lincoln, Joe Leithmann collected it.
