It isn't. The $50 dollar denomination is artificial.
Gold buffalo coins are bullion coins whose price is based on the amount of gold they contain. However by law all US Coins, even bullion coins, must carry a denomination. Because gold prices change daily, it's not possible to use a "real" denomination that reflects the coin's exact gold value. Instead, an arbitrary denomination is used based on the troy weight of each coin.
More information is needed. The U.S. minted real gold dollars in the 19th century and these can now be worth large amounts of money. The "goldEN" dollars minted since 2000 are made of brass, not gold, and are of course worth only $1. If you have one of the older real-gold dollars, please post a new question with the coin's date and mint mark, if it has one.
The value of a 1990 Eisenhower gold commemorative coin depends on the condition of the coin. On average the coin would be worth approximately $26.

You need to be more specific. There have not been any gold dollars released by the US Mint since 1889 for circulation (minus some minor collector editions before 1933) and there are no gold dollars dated 1978 struck by the US Mint. Instead you either have a gold plated 1978 dollar coin (which would just be worth $1) or you have a dollar coin issued by a different country or private mint.
That depends on factors such as the denomination, date, and condition. For example, a $10 gold coin is worth more than a $5 gold coin. At very least, there's value for the gold content.
