To determine the value of 1 dollar of gold in 1848 in today's terms, we need to consider the historical price of gold and inflation. In 1848, the price of gold was approximately $20.67 per ounce. Adjusting for inflation and the current market price of gold, which is around $1,800 per ounce in recent years, 1 dollar of gold in 1848 could be worth roughly $87 today, depending on specific inflation calculations and market fluctuations.
If you mean a US 1848 Seated Liberty dollar, low grade coins are valued at $300.00-$500.00 better grade are $700.00-$1,000.00 and up. I suggest having a dealer or collector grade the coin for a better idea of value.
