PERU. Lot of (2). Banco de Londres Mexico y Sud America. 1000 Soles, 18xx. P-S278p1 & S278p2. Front & Back Proofs. Very Good & Fine.A front and back pairing of proofs for this rare high denomination catalog number. For reference, although we are selling this lot uncertified, PMG has yet to grade this catalog number. The front proof has printers annotations. Both were previously mounted. The back proof has been damaged and extensively repaired. Overall, a rare piece which is surely missing from even the most extensive holdings of Peruvian paper money.
