Milled

Milled coins are those that have been produced using a mechanical press, or mill. The earliest British coins made by this method were the milled shillings et infra of Elizabeth I produced by the Frenchman Eloye Mestrelle from 1560 onwards. There were further experiments with milled coinage during the reign of Charles I by Nicholas Briot and later by Pierre Blondeau during the Commonwealth period in 1651. The coins depicting Cromwell were also struck by this method, but it wasn't until 1662 that they finally ceased to make hammered coins.  All coins made since then have been struck using presses.
