The 1975 United States Proof Set includes coins from 1975 & 1976. The Lincoln penny, Jefferson nickel, and Roosevelt dime are from 1975. The Washington quarter, Kennedy half dollar, and the Eisenhower dollar are from 1976 due to the fact that Bicentennial coinage was produced for two years. There is not a 1975 quarter, half dollar, or dollar in existence. The coins are packaged in a hard plastic airtight package. (2,845,450 minted) Older year Proof Sets may have been previously owned. If you need one of these proof sets in new condition, please call for price and availability.
