The phrase describes the worth of a United States quarter dollar coin minted in 1999 that is mistakenly or intentionally composed of, or plated with, gold. Instances of such altered coins generate significant interest among collectors, potentially commanding a premium beyond the face value of a standard quarter. However, it’s crucial to discern genuine errors from post-mint alterations to accurately determine any collectible merit.
Understanding the potential monetary worth requires a nuanced understanding of numismatics. The presence of precious metal inherently adds intrinsic value to a coin. Furthermore, specific mint errors can elevate a coin’s worth substantially. Historical context is vital because the circumstances surrounding coin production and alterations can affect collector demand and valuation.
