Your series 1988A $5.00 inverted serial number D70274893B was printed in March 1994.
The serial number is assigned to plate number H4, and since COPE trims the 32 subject notes in half vertically before printing the serial numbers, and this sheet was rotated 180° prior to the 3rd printing, the plate position on your error note should be A3.
The BEP used both COPE & LEPE Overprinting on the series 2009 f/w $1.00 notes... Both systems used a different numbering format, and the LEPE does not require cutting the sheets in half prior to serialing..
If your note has Plate position number A1, then it would also be considered a COPE switching error...
