Sergei Nikolayev Knurov, a chef in Ukraine, built this model sailing frigate. The 30-pound hull is made of 17,000 coins held together with a silicate glue. The sails are made of paper currency. According to Oddity Central, Knurov used mostly 2 and 10 kopek coins and 25 5-hryvnia banknotes.
Knurov and his wife, Alena, worked on the project together for 2-3 hours a day for 6 months. It cost them about 800 hryvnia ($77 USD) to build. They hope to sell it for about 4,000 hryvnia ($386 USD).
