Step 3: Annealing & Pickling: Gold coins made until now had gone through a harsh and raw environment where dirt is mixed with them. The riddler machine removes any extra material from it. These gold coin blanks are put in an annealing oven to soften them for striking. Also, they go through a chemical bath to remove oils or dirt present in them.
Step 4: Upsetting: Gold coins made till now are passed through a machine having a set of rollers to impart a raised metal rim on both sides. It also ensures the proper diameter, so the coins strike properly in the coming processes. These gold coins made now are called planchets.
Step 5: Striking or Stamping: The gold coins made till now are finally stamped by the ‘coining press’ or imprinted with the set designs.
Step 6: Inspection: In this step, inspectors check the gold coins made by the organisation using magnifying glasses. Here all flaws or faults (if any) are detected.
