Russian artist Roman Booteen (featured previously here and here) recently unveiled his latest ‘Hobo nickel‘ featuring a beating heart.
Using a US Silver dollar (Morgan), Booteen made a beating heart with a clever turning mechanism shown below. The coin is one-of-a-kind and Booteen has no plans to make any more of this design in the future. He says he will eventually put it up for sale/auction at a random time in the future.
