<P> There is also hard evidence that the US - variant phrase in print, is from the Olean Evening Times, March 1926 . That includes an item by Allene Sumner, headed My "Two cents' worth". </P> <P> "Two cents" and its variations may also be used in place of the noun "opinion" or the verb phrase "state (subject's) opinion", e.g. "You had to put your two cents in, didn't you?" or "But that's just my two cents ." </P> <P> This expression is also often used at the end of a statement, e.g. "Just my two cents ." </P>

Where did the phrase put your two cents in come from
