10 Reais 1st. Family, Watermark 'Flag'

The Plano Real, launched in July 1994, succeeded where several prior stabilization attempts had failed — the 10 Reais entered circulation as inflation was finally collapsing after decades of chronic monetary disorder. This note's long print run, spanning over a dozen years and six different signature combinations, reflects that unusual institutional continuity. Pedro Sampaio Malan's signature appears across the earliest series from 1997 through to the Lula-era handover at C1137C, an unbroken tenure at Finance that few economies see.

The Guido Mantega "not legible" variety at D3439C is a recognized collectible distinction — his signature block was reworked mid-series after legibility complaints, making the transitional prefix range genuinely scarce relative to surrounding issues.
