mall medallions up to about 40mm diameter are manufactured much the same way
as coins and the finish varies depending on the clients specification. The finish
may be "as struck" with the natural metal colouring, electro-plated in metals
such as gold and silver or given an antique appearance by using various
chemical treatments. Medallions with natural or antique finishes are usually clear
lacquered at the final stage to enhance and protect their appearance. Larger medallions, particularly those with deep relief require very high
pressures to form the designs. Hydraulic presses with capacities of up to 600 tonnes are
used to coin these medallions which may need to be struck several times with interstage
annealing (softening) between each strike.
