- Key
- As in key date. Usually the most important date or dates in a
coin series. Collectors aspire to own them and prices are therefore kept
high in relation to numbers known. Important key dates include 1909-S V.D.B.
Lincoln cent, 1796 half dollar, and 1895 Morgan silver dollar. (The 1881-S
Morgan dollar is not considered a key date by numismatists regardless of
what promoters may claim.)
