Detecting repaired coins
Usually, all an expert needs is a quick look at a coin to detect a repair. Sometimes, with the aid of a magnifying glass. But other times, the repair is good enough that it may be suspected (because “something” looks off) but not actually seen. In such cases, what technologies, equipment and methods can be used to positively determine what, if anything, was done to the coin?
