10 Soles de Oro Overprinted on P#49

P#57 is a provisional issue — an overprint applied to existing stock of the 10 Soles de Oro P#49 plates rather than a newly commissioned design. The Banco Central de Reserva del Perú resorted to this arrangement in 1935 as a stopgap while transitional printing schedules caught up with demand, a common enough practice in Latin American banking of that period but one that makes provenance tracking across the P#49/P#57 boundary genuinely tricky for collectors.

The American Bank Note Company had held the Peruvian account for decades by this point, and the watermark security was carried over unchanged from the parent note.
