5 Reais Olympic Games Rio 2016 - Cycling / Porpoises

Brazil's 2014–2016 Olympic commemorative program was one of the most ambitious in the mint's history, spanning dozens of issues across multiple series. This piece falls within the aquatic sports subset, though the pairing of a cycling theme with porpoises on a single coin reflects the program's occasionally idiosyncratic design pairings rather than any deliberate thematic logic. The Casa da Moeda do Brasil struck these well in advance of the Games to satisfy collector demand during the lead-up period — a common pre-event strategy that often results in lower secondary-market premiums once the games conclude and enthusiasm cools.
