@ash, just is mentoined by @j-tal above, surface toning such as on your coin is commonly due to chemical or environmental exposure and is therefore not a mint error. However, we also do see quite a few gold-plated coins posted here. This is always aftermarket with such a small amount of gold as to not enhance the value of the coin. Either way, your coin is kinda cool looking, but only worth face value.
