The 1987 $50 gold coin is basically just valued for its precious metal content. All that means is that the value of the coin will change depending on the current market value of gold. This is a one ounce coin. So it is worth what one ounce of gold is worth. Collectors refer to these as AGE or American Gold Eagles. The United States Mint markets these coins every year. The only difference is the year on the coin; all the other design elements are the same year to year. Whether we are talking about a coin issued in 1987, 2013, or any other year – you will always see the same features.
The 1987 one ounce coin has text that reads: MCMLXXXVII – Liberty – United States of America – E Pluribus Unum – In God We Trust – 1 OZ. Fine Gold ~ 50 Dollars – MB JW. The front or obverse of the coin pictures Lady Liberty holding a branch and torch. The back or reverse of the coin has a family of eagles.
