Your "public servants" at work. Weren't the bronzes in the First Spouse program mandated in the legislation that created the gold half ouncers? You have the entire gold set, right? Proof and BU both, right?
I think some of the British....oh you meant on that US mint page, well I will take none of them for $500 alex
IMO, The only 2 coins "worth" getting are the 1/2 ounce walking liberty (.9999) and the 1/4 ounce (.9999).
