An interesting example of a frothy market was Holland's tulip bulb market in the early 1600s. The market for tulip bulbs went through a huge run up and crash.
People mortgaged whatever they could to raise cash to trade tulip bulbs. In 1633, a farmhouse changed hands for three tulip bulbs. The market top came in the winter of 1636-37 when a single tulip bulb, left along with 70 other tulip bulbs as seven orphans' only inheritance, sold for 5,200 guilders. Soon after the top, tulip bulbs traded for 1/100 of what they had two weeks earlier.
