Why do coins smell funny after you touch them?

Some sort of chemical reaction maybe? Between your skin and the metal that is

From what I understand (Grandfather was a coin collector) it's the acid and oils from constant handling reacting with the metals. Older coins more so than newer, hence the tweezers and gloves. I wouldn't discount the coin farts though 😆

I think its an eletrical thing.
The salt and sweat in our hands along with our own minute eletrical. energy excites the zinc snd copper found in many coins.
Not to mention our hand anf their moisture heat the couns up a bit.

probably the oils and stuff from people's skin

🤔Residue perhaps.

Acid from your skin

It's from people not washing their hands after going number 1 or 2 that ought to make you think twice before ever doing that again 🤢

I am sure that cash naturally has that scent

I didn't know coins could smell anything... 🤓
