According to the Numismatic Guaranty Corporation (NGC), the most valuable 1929 peace dollar is the MS-68, with an estimated value of $125,000. This grade represents a coin that is in mint state, with no visible signs of wear or damage.
Other high-grade 1929 peace dollars, such as those graded MS-67 or MS-66, can also be worth several thousand dollars. However, even lower-grade examples, such as those graded EF-40 or VF-20, can still sell for hundreds of dollars.
The value of a 1929 peace dollar can also be influenced by its rarity. Some 1929 peace dollars are considered to be rare or semi-rare, which can increase their value. For example, the 1929-S peace dollar, which was minted in San Francisco, is rarer than the 1929-P peace dollar, which was minted in Philadelphia. As a result, the 1929-S peace dollar is worth more than the 1929-P peace dollar.
