I have a coin from the Philippines. It is a Jose Rizal 1 piso coin. There are two dates on it. On the front, the date is marked 1998, and on the back the date is marked 1993. It is a true printing error. There are no overlaps or anything. I'm having a hard time finding this coin or any information on it. If any of you could help, I would really appreciate it. I'd like to find some information on the coin and possibly find out what it is worth. Thanks guys!
