CONSEC PAIR: $2 1976 FRN Insufficient Ink Improper Batting Errors on Both - 2 Errors Gem

An "improper batting" error on paper money refers to a specific type of insufficient inking error that occurs during the printing process. The batting acts as a cushioned, woven fabric base between the impression cylinder and the printing plate, acting as a shock absorber under 32 tons of pressure. 

This consecutive pair of bicentennial deuces show evidence of the batting fatiguing near the lower left corner of the back. As a result, an insufficiently inked portion of the design is present. 

These errors aren't dramatic and take a more sophisticated appreciation than some other eye-catching mistakes, but think about how many gutter folds, offsets, and ink smears you've seen compared to improper batting errors....and don't forget, this is a consecutive pair on Gem $2 1976 notes.
