    1. Metallurgy of Coins Suhaylah Ali Nimmi Bhatt Roman Savinov Engineering 45 Fall 2010 Santa Rosa Junior College

    2. Production of Coins Planchet Metallurgy Die Steel Metallurgy Microstructures (our experiment) What about conclusion?What about conclusion?

    3. Planchet Metallurgy Planchets are round disks punched from large metal sheets. (blank coin) The sheets are formed from recycled scratch metal. After round disks are punched out, they undergo rim formation.

    4. Die Production Dies are stamps used to imprint images on coins. The size of coins Made of steel The imprint initially begins with a master art work which is then manipulated to fit the size of the die . The process of die production involves cycles of squeezing and annealing,in order to meet service requirements.

    5. Final Stage The final stage in coin production is stamping the planchets with these dies.

    6. Analysis of Microstructures Coins analyzed: That worked 5 euro cent 2 1 Deuchemark
