1776-1976. The distinct reverse designs make them popular as type

Here is one of three we're profiling in this Market Analysis series:
1976 Kennedy, Bicentennial half dollar, double

Error coins with off-center multiple strikes are popular because
they’re impressive and easy to understand. The collection included a
double-struck 1976 Kennedy half dollar with the coin shifted toward

obliterated by the second strike, leaving two partial portraits of the
president and two partial impressions of Independence Hall.

Kennedy half dollars worth?

intended for a Jefferson 5-cent piece, sold for $4,465.

Eisenhower dollar error is weird but desirable:
This is what happens when a planchet intended for a Washington
quarter dollar gets mixed in with Eisenhower copper-nickel dollar planchets.
