I have a Proof 1971-S Eisenhower clad dollar still in its Littleton
package. I can’t find a value for this coin in the “Red Book” or
Coin World’s Coin Values. Is this a rare coin? Any help
would be greatly appreciated.
No Proof Eisenhower copper-nickel clad dollars were struck in 1971
and 1972; they were minted from 1973 to 1978 only. Littleton Coin
Co.’s description of the coin (illustrated above) as a copper-nickel
clad piece (“CN Clad”)appears to be in error. It is likely an
Uncirculated or Proof silver-copper clad coin issued for collector sales.
The 1971-S Eisenhower silver-copper clad dollars (40 percent
silver) are not rare. The San Francisco Assay Office struck 4,265,234
Proof coins and 6,868,530 Uncirculated coins (a number much smaller
than the copper-nickel clad coins struck for circulation at the
Philadelphia and Denver Mints).
The value of 1971-S “Ike” silver dollars is largely based on their
silver content (80 percent silver, 20 percent copper, bonded to a core
of 21.5 percent silver, 78.5 percent copper, equaling an actual pure
silver weight of 9.84 grams/0.32 ounce). Only high-grade Proof and
Uncirculated pieces possess a noticeable numismatic premium beyond
their silver content.

I have 1971-D Jefferson 5-cent coins that differ in the placement
of their D Mint mark — some close to the date, others not. Are these
A “floating” Mint mark is a common occurrence on U.S. coins struck
prior to the 1990s.
The different positions of the Mint marks result from the hand
placement of the Mint marks on individual working dies until 1990 and
1991. Mint marks were hand punched on the working die up until those
years, so position can noticeably vary.
Unless the positioning of the D Mint mark is so great that it
touches another design element, such as the date, the coins carry no premiums.

staying tuned to Coin World’s “Collectors’ Clearinghouse” and
