I have two 1975 Proof sets. In one set, the coins are in red felt,
cased in a black plastic case. The other set is sealed in a plastic
wrap. Note the coins in the second set do not have the S Mint marks.
Can you give me some information regarding these sets?
From Mr. Benhoff’s description and the image provided, it appears
he possesses not two Proof sets but a 1975 Proof set and a 1975
Uncirculated Mint set.
The 1975 Proof sets were sealed in a clear plastic case with the
coins framed within by a red, felt-covered paper insert, all contained
within a black plastic frame. The Proof coins bear the S Mint mark of
the San Francisco Assay Office.
The 1975 Uncirculated Mint sets, however, were packaged in
pliofilm and were sealed in a simple white envelope bearing the words
“U.S. Mint/1975 Uncirculated Coin.” The Mint set contains
circulation-quality coins from the Philadelphia Mint in one pliofilm
holder and coins from the Denver Mint in the other holder, with the
Denver Mint coins bearing the D Mint mark.
The 1975 Proof set had an original issue price of $7, while the
1975 Uncirculated Mint set had an original issue price of $6.
Interestingly, the values of the two sets today are not much different
from their original issue prices.
Owners of a 1975 Proof set should be sure to take a close look at
the Roosevelt dime in the set. If it doesn’t have an S Mint mark, it
should be submitted to an expert for authentication. Why? Two known
1975-S Roosevelt, “No S” Proof dimes are known, and one of them sold
for $349,600 in an Aug. 18, 2011, Stack’s Bowers Galleries auction.
The 1975 Proof and Uncirculated Mint sets are also interesting as
they contain the dual-date 1776-1976 Eisenhower dollar, Kennedy half
dollar and Washington quarter dollar. These coins bear commemorative
reverses in honor of America’s Bicentennial. The only circulating U.S.
coins struck with the date 1975 are the Lincoln cent, Jefferson 5-cent
coin and Roosevelt dime.
The same holds true for the 1976 Proof and Uncirculated Mint sets,
whereas the cent, 5-cent coin and dime are dated 1976 and the dollar,
half dollar and quarter dollar again bear the 1776-1976 dual date.
Collectors should be aware of two different subtypes of 1776-1976
Eisenhower dollars — the Bold Reverse Letters, often termed Type I,
and the Thin Reverse Letters, often called Type II. Many hobbyists
like to collect an example of each subtype.
