 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.One possible explanation for this change in the pattern of production and hoarding is that it came to be the rule, after the 1030s, that only payments to the crown had to be in the current type, whereas other types of English coinage were viable for other purposes.
