Little cracks on silver ancients are of two types:
1. - flan cracks when the coin has been struck; these are usually radial, at the edge, but not necessarily, and:
2. - natural aging of the silver itself, which can be of two sorts:
silver crystallization and
horn silver.
Silver coins, like humans can get old, and eventually fall apart.
