Selected title: Universal Rarity Scale
Explanation: A collectibles rarity information scale developed in 1998 by 21 major collectibles experts in order to both define rarity within their individual markets and allow collectors and dealers from different collectibles markets to more easily communicate with one another. The Universal Rarity Scale is a 10 point scale. The least rare collectible items are those where more than 10,000 examples are estimated to exist. These items are designated 'UR1' and are described as 'readily available.' The rarest items are those where only one example is known to exist. These rarities are designated 'UR10' and are described as 'unique.'
