In 2015 to celebrate the 20th Anniversary of Back to the Future, the Perth Mint on behalf of the issuing country of Tuvalu released a very Limited Issue DeLorean $1 One Dollar Silver Proof Coin struck in solid fine .999 Silver and weighing one ounce of pure Silver.
The reverse design depicts a DeLorean DMC-12 Sports Car from Back to the Future surrounded by lightning bolts with the Hill Valley Courthouse in the background while the obverse bears the elegant portrait of Her Majesty Queen Elizabeth II by Ian Rank Broadley.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
