Also worth noting, some Sainsbury supermarkets (and I'm sure other
places) have machines that will take any amount of small change, to be
either credited to an account, or paid back in larger denomination
coins/notes.

Best bet is to be married to the Church treasurer who never minds
changing shedloads of pennies on a Sunday night!
