Dead man's hand
The make up of poker's dead man's hand has varied through the years. Currently, the dead man's hand is described as a two-pair poker hand consisting of black aces and eights. Along with an unknown "hole" card, these were the cards reportedly held by "Old West" folk hero, lawman and gunfighter, Wild Bill Hickok, when he was assassinated.
Earliest details 
The expression "dead man's hand" appears to have had some currency in the late 19th and early 20th centuries, although no one connected it to Hickok until the 1920s. The earliest detailed reference to the "dead man's hand" was 1886, where it was described as a "full house consisting of three jacks and a pair of tens". Jacks and sevens are called the 'dead man's hand' in the 1903 Encyclopaedia of Superstitions, Folklore, and the Occult Sciences Edmond Hoyle references the Dead Man's Hand as "Jacks and eights" in 1907.
Hickok's hand 
What is considered the dead man's hand card combination of today gets its notoriety from a legend that it was the five-card draw hand held by James Butler Hickok (better known as "Wild Bill" Hickok) when he was shot in the back of the head by Jack McCall on August 2, 1876, in Nuttal & Mann's Saloon at Deadwood, Dakota Territory. Reportedly, Hickok's final hand included the aces and eights of both black suits.
The make-up 
According to a book by Western historian, Carl W. Breihan, the cards were retrieved from the floor by a man named Neil Christy, who then passed them on to his son. The son, in turn, told Mr. Breihan of the composition of the hand: "Here is an exact identity of these cards as told to me by Christy's son: the ace of diamonds with a heel mark on it; the ace of clubs; the two black eights, clubs and spades, and the queen of hearts with a small drop of Hickock's blood on it."
Hickok biographer, Joseph Rosa, wrote about the make-up of the hand: "the accepted version is that the cards were the ace of spades, the ace of clubs, two black eights [clubs and spades], and the queen of clubs as the 'kicker' [card]." However, Rosa said no contemporaneous source for this exact hand can be found. The solidification in gamers parlance of the dead man's hand as two pair, "aces and eights", didn't come about until after the 1926 publication of Frank Wilstach's book, Wild Bill Hickok: The Prince of Pistoleers—50 years after Hickok's death.
The fifth card 
In accounts that mention two aces and eights, there are various claims regarding the identity of Hickok's fifth card, suggestions that he had discarded one card or that the draw was interrupted by the shooting and Hickok therefore never received his fifth card.
Historical displays in the town of Deadwood, including one in a reconstruction of the original saloon, display the nine of diamonds as the fifth card. The Lucky Nugget Gambling Hall, at the historic site of Nuttal & Mann's Saloon, displays a jack of diamonds instead. The Adams Museum in Deadwood has a display that claims to be the actual Bulldog Squeezers Playing Cards held by Hickok (ace of diamonds, ace of clubs, eight of hearts, eight of spades, and the queen of hearts). The old Stardust Casino on the Las Vegas Strip had used a five of diamonds in related displays.
The Las Vegas Metropolitan Police Department Homicide Division uses the dead man's hand in its insignia, as does the Armed Forces Medical Examiner System.
