It is said that a large part of the monks treasure from Kilwinning Abbey was found at Montgreenan circa 1740 by the laird, consisting of seven crocks of coins, rings, brooches, candlesticks, crosses, necklasses, pomanders, beads, etc [REF].
John Smith in 1895 recorded that a pot of silver coins was found in the Chapel Park, on Montgreenan lands (NS 343 445).
