$2 1976 Mismatch Error
PMG Choice Uncirculated 64 EPQ
The only available variety of a mismatch on a $2 bill. This note ends 518A on the left and 618A on the right.
A sixth-digit mismatch on a deuce! Not surprisingly, this escaped the BEP without detection; however, the true triumph was that it managed to escape circulation without any evidence of handling.
A rare and exciting deuce error to add to any collection.
Fr. 1935-B with signatures from Neff and Simon
This note has a
MISMATCHED SERIAL NUMBER
B 592085/618 A
This is a very popular mistake, but on a rare denomination!
Mismatches are an important and necessary part of every "type"
collection of error notes. While they are rather subtle, most escape and enter circulation before being spotted--any high-grade example is a genuine exception.
Mismatches occur in one of two ways: either the press operator fails to properly set the two independent numbering wheels in synch (this generally reflects a mismatch at the beginning of the serial number) or the numbering wheel sticks on one side and continues to advance normally on the other.
Some mismatches have only one or two known, those are extremely rare and extremely valuable because of the few known; others have many known--which makes them perfect choices to serve as a examples of the error.
Some collectors attempt to acquire:
--one of each known variety
--one example from each denomination
--one of each type and denomination of FRN and SC including
Both mismatched serial numbers and mismatched prefix/suffix letter
--one of different high-grade examples
--or--simply one of whatever strikes the collector's fancy as opportunity and resources permit
