Before the elimination of the Gold Standard, these notes were Silver Notes. Just as they say "This note is legal tender for all debts, public and private" they once also stated that you could take this note to any bank and receive Gold/Silver for it (depending on the current exchange rate). This is no longer, obviously, doable as we no longer peg the value of our currency on the value of Gold.
