Peru experimented with holed coinage in 1947 as part of a broader postwar review of circulating denominations, but the perforated 2 centavos never entered production. The practical motivation was material economy — a punched-out center reduces copper content per coin — but the design was ultimately rejected in favor of the solid format already in use.
Pattern survivors are rare by definition, existing only as mint trials without a production run behind them.
