Coin roll hunting

An example of a potential find in 'CRH': A silver Canadian dime, found in a box of forty dollars worth of American dimes

Coin roll hunting (often abbreviated as CRH) is the hobby of searching and sorting coinage pulled from circulation for collectible coins. This is achieved through obtaining rolled coin, boxed coin, or bagged coin from banks and credit unions. A variant of this practice involves banknotes and is carried out in essentially the same fashion, normally to search for unusual serial numbers, star notes, and misprints.
