Yes - I have a set of 1970 pre-decimal coins, containing halfpenny, penny,
threepence, sixpence, shilling (English and Scottish versions), two
shillings, and half crown. Some of these were not minted for general
circulation in that year.

None of them were minted for general circulation, though presumably
the 6d, 1s and 2s were legal tender. Sets are reasonably common and
come up on Ebay all the time.
