Pieces of eight were counter-stamped and circulated globally, impacting multiple regions.

Evidence

In the coin collection of the British Museum there is a display that gives a wonderfully clear idea of the global role of pieces of eight made in the Spanish-American mints. … One coin has been counter-stamped by a local sultan in Indonesia, while others were stamped by the Spanish themselves for use in their province of Brabant, now in modern Belgium. — Neil MacGregor, A History of the World in 100 Objects, 1234
