 The weight of the coinage varied considerably, even within types, suggesting that there may have been some profit taken in minting by extracting silver from the coinage, though within the kingdom of England it would have been possible to enforce that all coins be accepted at face value regardless of weight.Hoard evidence, at least from before the 1030s, suggests that reminting of the whole coinage was stipulated at each change of type, for a number of hoards survive consisting of only one type.Alongside these, however, are 'savings' hoards, which contain a mixture of two or more types; and a mixture of types becomes much more common in hoards from after the 1030s.
