Coin set
A set of coins
A coin set, or mint set, is a collection of uncirculated or proof coins, released by a mint. Such sets are usually released annually and often called a year set. They include sets of all the circulating coins of that year, as well as sets of commemorative coins.
A coin set also describes a group of coins assembled by a coin collector. Collectors usually try to find all of the dates and mint marks in a series to fill out their coin set.
