Copper plating zinc coins and souvenirs

I am a retired and bored lawyer. Recently through try and error have reproduced, coins, medals and other objects using zinc in the lost wax procedure. I would like to copper plate some of the mentioned objects, in a simple home hobby shop. Electrolysis could be an option if instead of a car battery I could use my current converter, the kind used for audio equipments. (12 volts). Any suggestions and informations would be appreciated
