In June of 1688, Portuguese authorities ordered the revaluation of all silver coins validated for circulation under a March 1663 edict. Underweight and clipped pieces were withdrawn and melted, while specimens that were of sufficient weight were restruck by a circular countermark and edge pattern, to discourage further alterations. Curiously, the legends that appeared on the initial issues were reused, resulting in coins in the names of João IV and Alfonso VI being effectively restruck after their deaths.
