MULTI-COLOR COIN AND MAKING METHOD THEREOF |
摘要 |
The coin made of different materials in more than two colors presents a good appearance and makes forgery difficult. A metal raw coin material is plated to form a plated layer (2) to be punched to trim the rim and stamp a pattern in carving. The plated coin may be plated over the first plating to form another plating layer and show a different color.
