Will Rogers? Eddie Cantor? Benjamin Franklin? Anonymous?

Question for Quote Investigator: Risky investments offer high returns, but the money invested may be completely lost. A family of statements uses wordplay to express a memorable warning. Here are three instances:
(1) I learned to worry about the return of my money instead of the return on my money
(2) I’m not so much interested in the return on my principal as I am in the return of my principal.
(3) I am not as concerned about the return on my investment as about the return of my investment.
The wordplay consists of repeating a template phrase while swapping the prepositions “of” and “on”. This quip has been attributed to U.S. humorist Will Rogers, U.S. comedian Eddie Cantor, and U.S. statesman Benjamin Franklin. Would you please explore the origin of this family of statements?
Reply from Quote Investigator: The phrasing of these statements is highly variable; hence, this family is difficult to trace. The earliest instance of this wordplay found by QI appeared in April 1920 in “The New York Times” within an advertisement for Prudence Bonds from Realty Associates Investment Corporation. The bonds offered 6 percent interest, which was not the highest rate available, but the advertisement emphasized the safety of the bonds. Boldface added to excerpts by QI:1
Of course, you can get a bigger return on your money, provided you accept a reduction in security.
But please bear this in mind: When we talk of the 100% soundness of Prudence-Bonds, we have in mind, not only the return on your money, but the return of your money.
In April 1920, the same advertisement for Prudence Bonds appeared in other newspapers such as the “Brooklyn Daily Eagle” of Brooklyn, New York.2
QI hypothesizes that an anonymous copywriter crafted this wordplay. Citations presented further below indicate that the popular entertainer Eddie Cantor used the same wordplay in 1933 and 1934. Cantor’s formulation placed more emphasis on wistful humor.
Will Rogers died in 1935. He posthumously received credit for a version of this quip by 1938 within a real estate advertisement. Overall, QI believes that the evidence linking Rogers to the quip is very weak.
Benjamin Franklin died in 1790. He implausibly received credit for a version of this quip by 1966 within a financial advertisement.
Below are additional selected citations in chronological order.
