5 Centavos smooth edge, magnetic

Argentina's monetary authority switched the 5 centavos to a magnetic brass-plated steel blank around 2006 as part of a broader effort to cut production costs following the catastrophic 2001–2002 peso collapse, which had wiped out the country's financial system and left the mint scrambling to rationalize coin production for years afterward. The smooth edge distinguishes this subtype from the reeded earlier issues — a detail that catches even experienced collectors off guard when sorting bulk Argentine material.
