A hoard or "wealth deposit" is an archaeological term for a collection of valuable objects or artifacts, sometimes purposely buried in the ground, in which case it is sometimes also known as a cache. This would usually be with the intention of later recovery by the hoarder; hoarders sometimes died or were unable to return for other reasons before retrieving the hoard, and these surviving hoards might then be uncovered much later by metal detector hobbyists, members of the public, and archaeologists.

An artifact or artefact is a general term for an item made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, the word has become a term of particular nuance and is defined as an object recovered by archaeological endeavor, which may be a cultural artifact having cultural interest.
