“Money talks” (meaning that money has influence) is an old financial saying, cited in print in various forms from before 1700. “Money talks” was printed in several American newspapers in 1868. 
 
American poet and author Richard Armour (1906-1989) wrote the following: 
 
“That money talks
I won’t deny.
I heard it once.
It said, “Goodbye.”
 
Although Armour popularized this version of the proverb “money talks,” the following was published in the Philadelphia (PA) Press in 1904:
 
His Experience.
That “money talks” I’ll not deny
May be quite untrue.
But it more often says “Goodby”
Than “How-dy-do.”
—Philadelphia Press.

Wikipedia: Richard Armour
Richard Willard Armour (July 15, 1906 – February 28, 1989) was an American poet and author who wrote over sixty-five books.
(...)
Armour wrote funny poems in a style reminiscent of Ogden Nash. These poems were often featured in newspaper Sunday supplements in a feature called Armour’s Armory. Many of Armour’s poems have been repeatedly and incorrectly attributed to Nash. Probably Armour’s most-quoted poem (often attributed to Nash) is the quatrain: “Shake and shake / the catsup bottle / first none’ll come / and then a lot’ll.” Another popular quatrain of his, also usually attributed erroneously to Nash, is: “Nothing attracts / the mustard from wieners / as much as the slacks / just back from the cleaners.”
