Whit is this?

I don't think it has anything on the back side and it has small ridges
Around its edge. Thanks for the help.

My guess is a trade token. Used for transactions in a store.

Maybe, it was in the yard at a 1811 built house, lots of old rail road spikes, a really old lock and a pocket watch were also found. Even a C R Tax Paid metal tag with 1870 on it. Not sure what C R is.
It looks like English and another language mixed together. I can see "No.3" and a Z or two but the rest are something else. Thanks.

I'm thinking its an adjustment knob from a lantern or glass oil lamp

Interesting, that has not crossed my mind. I did find two old lamp burners near this area. I will check them to see if they are missing there knobs. I would think it is a little to thick to be one, but possible.

Welcome to Treasure Net !
I like "ironhorse's" response.
I would call it a wick raiser knob or wick adjustment knob.
