Yup, it's a wet ink transfer. Right after the notes are printed, they are stacked one on top of another (in huge sheets). Some of the ink doesn't dry as quickly, so when they are stacked, the weight from the other notes press the wet ink into the note below it.
haha for $5? I'll be a pal and give you double that.
But your 88A series (quite rare now!) looks to be in high XF+ grade (no folds I see or considerable wear) so I'd give it around $30-50 or so. The market for these notes not like other notes, because they're rare and there isn't an established price for them. Guess it depends on who wants to pay what, but I'd give about $30-50 for it.
