Key Date Coins

A key date coin is one of a series which is either scarce, rare, or much less common than most of the other dates in the series. When collectors or dealers pick through a large quantity of coins to form a complete date collection, it is always the "key date" which they find hardest to get. A key date coin is also usually the lowest mintage of the denomination or series.

Semi Key Dates
Some dates are not quite as scarce as others, but still not as common as most dates, and these are often referred as semi-key dates.
