Avoid Price Bubbles. The rare coin market is just as volatile as any other free-market. Ultimately coin prices are determined by supply and demand. The discovery of a coin horde can dramatically affect the price of coins. For example the sale of the GSA silver dollars in the 1970s made many previously "rare" Morgan silver dollars "common" when thousand coin bags of them were put on the market. This sudden influx of supply dramatically pushed the price of many rare Morgan silver dollars down to that of a common silver dollar.
