Do all ancient coins hold collector value?
The same rules of numismatics govern ancient coins as well. Collector value is based on rarity, condition and market factors; age does not contribute to value. Since mintage figures are unknown, there is a relative amount of uncertainty involved in collecting ancients. A valuable coin previously believed to be rare can have its value usurped by the discovery of a hoard of the same type of coin. There are many sources specific to the study of ancients. Some can be found in public libraries, but the ANA MoneyMarket carries a full line of publications that can help you identify and evaluate your ancient coins.
