OK, this is kind of like asking what's a "Henway"? The
ASE and AGE were meant to be bullion coins and therefore track the spot price of the metals. Even today, the bullion coins have some numismatic value because of mintage and availability. The base price will always be the spot price of the metal. The rest of the story will be what the market will bear for the coin.
As for the "Henway"...about 3 pounds.
