* Condition: The condition of a coin is one of the most important factors that determines its value. Coins that are in good condition, with no major damage or wear, are worth more than coins that are in poor condition.
* Rarity: The rarity of a coin also plays a role in its value. Coins that are rare are worth more than coins that are more common. 1789 silver dollars are considered to be rare coins, as only a small number were ever minted.
* Market demand: The market demand for a coin also affects its value. Coins that are in high demand are worth more than coins that are not as popular. 1789 silver dollars are in high demand among coin collectors, which helps to increase their value.
Based on these factors, the value of a 1789 silver dollar can range from a few hundred dollars to several thousand dollars. In some cases, especially rare and well-preserved specimens can sell for even more.
