Additionally, the mintmark can affect the value of the coin. Coins minted in San Francisco (S), Denver (D), or Philadelphia (no mintmark) are all valued similarly. However, coins minted in Philadelphia with a "D" mintmark are much rarer and can command higher prices.
These prices are approximate and may vary depending on market conditions and the specific condition of the coin.
It's always a good idea to have a rare or valuable coin authenticated and graded by a reputable third-party grading service like the Professional Coin Grading Service (PCGS) or the Numismatic Guaranty Corporation (NGC). This can help ensure the accuracy of its condition and value.
