At the peak of tulip mania in February 1637, some single tulip bulbs sold for more than 10 times the annual income of a skilled craftsman. It is generally considered the first recorded speculative bubble (or economic bubble), although some researchers have noted that the Kipper- und Wipperzeit episode in 1619-22, a Europe-wide chain of debasement of the metal content of coins to fund warfare, featured mania-like similarities to a bubble. The term "tulip mania" is now often used metaphorically to refer to any large economic bubble (when asset prices deviate from intrinsic values).
