Most of the brockages that I have see on 18th and 19th century coins have been brockages, on of the first couple of strikes struck through a coin stuck to a die. Most of the modern "brockages" I see are what I would call struck through a mid stage capped die where the design on the stuck coin is already spreading and distorting.
It may be because the presses used to run slower and the operator would notice the problem and correct it before the cap had a chance to spread that much.
