In 2014 to celebrate the cartoon character series The Flintstones, the Mint of Poland released a very special Limited Issue Flintstones $1 One Dollar Silver Proof Coin struck in solid .925 Sterling Silver.
The reverse depicts Fred, Barney and Elmo, the Bedrock Family from the Flintstones while the obverse features Ian Rank Broadley's portrait of Her Majesty Queen Elizabeth II. These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
