I recently received my order of ten Kangaroos and while checking out all the little details around the coin I found that the Dan Thorne initials are doubled. There is also a line along the right side of King Charles' head that looks like possible doubling. Is this kind of doubling worth more than just spot price of the silver? If so, what kind of premium does it get, worth sending in for grading, should I store/treat them differently than if they were normal bullion coins?
