Philadelphia, Pennsylvania. Bank of Pennsylvania. ND (18xx). $500. Uncirculated. Proof.(PA-480 G200 SENC). Underwood, Bald, Spencer & Hufty. India paper only. Upper left, the Pennsylvania arms. Left and right, vertical 500 panels, corners with cameo heads. Extremely rare high denomination proof from a venerable American bank. There was one sheet in the 1990 ABN sale with two impressions. This is likely the Plate A example from that sale. Prior mounting evidence is seen in the back top corner otherwise dark inks and plentiful margins are seen. We sold the Plate B example for $3290 in our August 2013 ANA auction.
