PLEASE NOTE: The value of a coin or paper currency is dependent upon the condition, or "grade" of that item. Since grading is a subjective process, there is risk in acquiring coins or currency whose grades have not been independently certified by one of the leading independent coin grading services. The numismatics market is subject to substantial fluctuations, including significant and rapid increases and decreases in value from time to time. Investors must be able to assume the risk of such price fluctuations.
