CB. Coin 1 Penny Token Opening Of the Sydney Railway 1855 Australian Tea Mart Medal

This coin is a total error in 1855, the material that was printed should be silver and gold, not a mixture of copper and iron. So it is declared a total error, it should be destroyed and not sold freely, but there are people in the employees who keep this coin. After retiring, the employee sold it through an auction at a very fantastic price.
