The value of a 1889 US silver dollar can vary depending on its condition, rarity, and any unique features it may have. As of current market values, a circulated 1889 silver dollar is worth around $23-$30. However, if the coin is in uncirculated or highly graded condition, its value can be significantly higher.
There's no such coin. An 1889 US silver dollar was minted for spending, not for investment, and was very different from modern "silver eagle" coins that do contain 1 oz. of silver. Morgan dollars contained one dollar's worth of silver, about 0.77 troy ounces at the time. The coins' inscriptions indicate their value (ONE DOLLAR on the back) and not their silver weight.
