Whitburn, Roman coins

Roman coins have been found on at least 2, perhaps more, occasions at Whitburn. 1) In the mid-17th century, in a sandhill on the coast, "A peckful...all Roman emperors...all of brass...about the bigness of half-crowns". 2) Perhaps the same as the above, bronze coins of the Constantine family have been recorded, with Maxentius, Licinius and Maximianus all recorded. 3) In 1889, among "gravel taken from the harbour quarry top at Whitburn", two first brass coins, one of Trajan, the other of Hadrian.
