John Jones's Dollar by Harry Stephen Keeler:

"A clever tale, the numerical results of which were computed by logarithms, is this story of a modest silver dollar deposited by a far-seeing old socialist, in the year 1914, to his fortieth descendant, who never was born."
(From Visaphone from 'John Jones Dollar' by Harry Stephen Keeler)
(Published in Amazing Stories in 1927)
