10 Centavos Prova

正面描述	Two fishes depicted in the central field, rendered in fine naturalistic detail with clearly engraved scales, fins, and facial features; the pair are arranged in a dynamic, interlocking composition facing opposite directions. The legend BRASIL curves along the upper portion of the coin in bold incuse Latin letters. The design occupies nearly the entire field, with a plain inner rim bordering the motif.

附加信息	Casa da Moeda do Brasil issued pattern strikings — designated prova in Brazilian numismatic terminology — as internal authorization pieces before committing to full production runs. The 1979–1980 window for this type coincides with Brazil's monetary adjustments under the military government of João Figueiredo, the last of the generals to hold the presidency, who inherited an economy careening toward the debt crisis that would detonate in the early 1980s. Stainless steel was being evaluated as a cost-control measure across the centavo denominations during this period. Whether this specific composition was ultimately adopted or rejected informs much of the type's collector interest.
