Coin Series
A coin series is a group of related or similar coins issued or presented together. Coin Series are usually sold or presented as a unit, they are physical objects. Coin series make it easier to track individual coin items and provide a system to present them.
In Turathium repository coin series are considered items (not item sets like collections and periods), they are presented through series item pages showing properties that identify and describe the related series. Like coin items they can be grouped together to form an item set or a collection.
In general coins in circulating and special coin series are arranged chronologically and from the small denominator to the large one.
