If you are talking about the current US $1 presidential series of coins, no. Such coins are struck in brass and lots of them were minted. Other than finding an error coin, those coins will only be worth $1 for the near (and most likely far) future. If you are talking about a coin set not made by the US mint, those sets very often do not appreciate in value past the value of the metals used to strike them.
