Factors that affect the value of a 1933 US silver dollar include:
* Mint location: 1933 silver dollars were minted in Philadelphia and Denver. Philadelphia Mint coins are more common and therefore less valuable than Denver Mint coins.
* Condition: The condition of the coin is important in determining its value. Coins that are circulated, even if they are in good condition, are worth less than uncirculated coins.
* Luster: The luster of the coin is another important factor in determining its value. Luster is the shine or brilliance of the coin's surface. Coins with good luster are worth more than coins with dull luster.
* Strike: The strike of the coin is also important. The strike is the sharpness of the coin's design. Coins with a sharp strike are worth more than coins with a weak strike.
Here are some approximate values for 1933 US silver dollars in different conditions:
* Good condition: $200 to $300
* Very good condition: $300 to $400
* Fine condition: $400 to $500
* Uncirculated condition: $500 to $1,000
* Certified uncirculated condition: $1,000 and up
