I’ve always wondered what makes money smell the way it does, and how it retains it even through years of circulation. Is it the paper, something they do at the Federal Reserve Banks, or what?

Well, both the paper and the ink are pretty unique, but I’m going to go with funneefarmer: money smells that way because it’s dirty from being handled by so many grubby hands.
I think the OP refers to the smell of new money, and that has everything to do with the paper and ink. The paper itself is very distinctive. It is made by only one company and is used exclusively for US currency. The high cotton fiber content gives currency paper a different aroma than, say, your average legal pad. That, in combination with the inks, creates that money smell.

Heavily circulated bills also seem to have a distinct scent, which is amazing considering all of the different people & places it winds up with/in.
It’s probably just the cumulative odor of hundreds & thousands & millions of dirty, grubby, nose-picking, but-scratching, disease-ridden hands. Don’t inhale too deeply…
