CALGARY COIN IMAGE AND DESCRIPTION of Crystallization.
Crystallization is a natural process that occurs to many silver coins over time. The purer the silver, the more likely they are internally crystalline.
The surface of a coin is highly stressed during striking and stressed metal normally does not crystallize. Internally the less stressed metal can be heavily crystallized over a perfectly smooth skin with no crystals exposed. When part or all of the skin is removed by corrosion, abrasive cleaning or even chipping, one gets exposed crystals as on this early Persian siglos. Appearing similar to corrosion, these crystals form a regular pattern, rather than random holes of corrosion. The effect on the esthetics is similar to mild corrosion, so the effect on the value is also similar.
