the Berasit Hebrew Dictionary

כספ

'kecep' means “coins” as currency and a symbol of economic purchasing power.

Some traditional translations include some instances where 'kecep' is erroneously translated as “silver”, a metal from which objects can be made. This interpretation does not stand up to contextual and etymological scrutiny. In 99% of the 417 instances, the usage is very consistant and clear that 'kecep' refers to currency, not metal.
