Miser's Dream is a classic coin production routine in which coins are plucked from thin air and dropped into a bucket.
The name of the routine was imported by T. Nelson Downs in 1895, which was previously had been known as "Aerial Treasury".
This was also used long before by de Linski under the name Le Rêve de l'Avare (See L'Illusionniste, vol. 1, No. 3, march 1902, page 4.)
Robert-Houdin was doing his version called "Shower of Money" by 1852.
