1992-1998 Full Run US Mint Premier Silver Proof Sets - 35 Coins Total, 7 Sets Over 4oz Of Pure Silver. Premier Silver Prood Sets include the same coins as standard Silver Proof Sets, but packaged in a premium display-type case. The plush, improved packaging and similar pricing make the premier sets an undervalued item in our opinion. Produced at the San Francisco Mint, these proof sets contain a Lincoln Cent, Jefferson Nickel, Roosevelt Dime, Washington Quarter and Kennedy Half Dollar. All Denominations above the Nickel are 90% Silver.
