In contrast to coins used by counting (counted currency), coins used by weighing are called weighed money. Items such as silver ingots or sycees, which vary in shape and weight, must be weighed to determine their value.
The weighing method is cumbersome, but one does not need to trust a face value. In places where the issuing authority is not trusted, this method prevails.
