What is the value of an Eisenhower Dollar?

Answer 1

If it's cupronickel clad and from circulation, face value. Uncirculated or Proof, $3 to $8 depending on year and mint mark. See http://www.numismedia.com/fmv/prices/ikedlr/pricesgd.shtml , among many similar sites. If it's one of the 40% silver coins minted for collectors, it's worth at least $5 for its melt value, more if it's still in its original package.
None of the Eisenhower dollArs regardless of date or mintmark struck for general circulation have more than face value. Only proof and uncirculated collectors coins sold from the Mint have premiums.
