The half dime, or half disme, was a silver coin, valued at five cents, formerly minted in the United States.

Some numismatists consider the denomination to be the first coin minted by the United States Mint under the Coinage Act of 1792, with production beginning on or about July 1792. However, others consider the 1792 half disme to be nothing more than a pattern coin, or 'test piece', and this matter continues to be subject to debate.

These coins were much smaller than dimes in diameter and thickness, appearing to be "half dimes". In the 1860s, powerful nickel interests successfully lobbied for the creation of new coins, which would be made of a copper-nickel alloy; production of such coins began in 1865, and were struck in two denominations — three and five cents (the latter introduced in 1866).

The introduction of the copper-nickel five-cent pieces made the silver coins of the same denomination redundant, and they were discontinued in 1873.

The following types of half dimes were produced by the United States Mint or under the authority of the Coinage Act of 1792:

In the Woods is a 2007 mystery novel by Tana French about a pair of Irish detectives and their investigation of the murder of a twelve year old girl. The novel won several awards such as the 2008 Edgar Award for Best First Novel By An American Author, the 2008 Barry Award for Best First Novel, the 2008 Macavity Award for Best First Mystery Novel, and the 2008 Anthony Award for Best First Novel.

Twenty years prior to the novel's events, twelve year-old Adam and his two best friends failed to come home after playing in the familiar woods bordering their Irish housing estate. A search is called by the families, and the police find Adam shivering, clawing the bark of a nearby tree, blood on his shoes and slash marks on his back. He is unable to tell them what happened or where his friends are. His amnesia holds to the present day, where he goes by his middle name, Rob, to avoid the attention of the media to his famous case. His friends were never found.

The plot of the novel circles around the murder of a twelve year old girl, Katy Devlin, whose case Rob and his partner Cassie Maddox are given to investigate. The body is found in the same woods where Rob’s friends disappeared, at an archeological dig site, and the coincidence is enough to make Rob nervous, though he insists to his partner that he is fine.
