For starters, the US dollar as a unit of currency isn't worthless by any means. When economists say that the dollar is losing value, they're talking about a generic item representing all forms of US currency and not a specific coin or bill.
In fact that generic dollar IS worth much less than it once was in comparison to other currencies, due to fears among bankers, investors, etc. that the country won't be able to solve its economic problems.
As far as individual purchasing power goes, in the US Coins and bills are completely interchangeable. If for example a flat-screen TV costs $1000, that TV theoretically could be paid for with 100,000 pennies, 10,000 dimes, 1000 $1 coins, or ten $100 bills. The problem is that if exchange rates change and the US dollar buys fewer Chinese yuan or Korean won, that TV's price may increase to say $1200. Then it would take 12,000 dimes, 120 Benjamins, etc. to buy it so ALL forms of US currency would have lost value in sync with one another.
Aside from the one dollar coin, other coins have a face value of less than one dollar. In the past, there were larger value coins, but they haven't been used since the 1930s.
There were no dollar coins minted that year.
1998 dollar coins may be worth more than 1997 dollar coins due to factors such as mintage numbers, rarity, and collector demand. If fewer 1998 coins were minted compared to 1997 coins, the 1998 coins may be more valuable. Additionally, if there is a higher demand for 1998 coins among collectors, their value could increase. Other factors such as the condition of the coins and any historical significance may also contribute to differences in value.
This question comes up fairly often and is a common misunderstanding. What you almost certainly have is a HALF dollar (check the back!!) that carries the same front-side design as modern 1 oz bullion coins issued since 1986. Those half dollar coins are called Walking Liberty halves and they don't contain 1 oz of silver. They were ordinary circulation coins meant for spending. There's more information at the Related Question.
