Based on general numismatic knowledge, as the provided context does not contain specific data, the value of a 1921 Morgan silver dollar in "Good" condition is primarily determined by its silver content. The year 1921 is the most common for Morgan dollars, with massive quantities minted in Philadelphia (no mint mark), Denver (D), and San Francisco (S).
In coin collecting, "Good" is a formal grade (G-4 on the numismatic scale) indicating a heavily worn coin where the main design elements are visible but most fine details are gone. For a common-date coin like the 1921 Morgan, this low grade means it holds very little numismatic premium over its intrinsic silver value.
A Morgan silver dollar contains 0.7734 troy ounces of 90% pure silver. Therefore, its base value fluctuates daily with the spot price of silver. Typically, a dealer might sell a 1921 Morgan in Good condition for a small premium over its silver melt value. Depending on the current market, this usually places its worth in the $25 to $35 range. For an exact price, it is always best to consult a reputable coin dealer or check the current price of silver.
