So where does the expression "just my two cents" come from?

i asked my good buddy jeeves and he said...

In any case, the whole point of "my two cents worth," which originated in the late 19th century, is that it is a faux-modest, self-deprecating tactic used to disarm your audience before you announce your opinion. This is especially important in the event that your opinion turns out to be idiotic, in which case you can always claim that you warned your listeners in advance that your opinion was next to worthless.
