How did a large supply of common ancient coins affect their prices?

In the context of coin collecting, a large supply of common ancient coins has a direct impact on their market value. Because many of the most common types of ancient coins exist in great quantities, they saturate the market, which results in very low prices for these specific types.1

This abundance makes ancient coins accessible to entry-level collectors, who can often acquire them quite inexpensively. Conversely, the market dynamics are such that while common coins remain affordable due to their high availability, the prices for very rare coins escalate significantly, making them difficult and expensive for even seasoned collectors to obtain. This relationship between supply and value is a fundamental aspect of the numismatic market, where scarcity remains a primary driver of an object's worth.12
