Ancient coin or replica? [opgelost]

Hi, i found this button made out of an coin.
It is a valuble replica or cheap fake?
Tell me the pricing please.

Hi,
no idea on value but in my opinion it's not made from a real roman coin.
Lettering refers to Severus Alexander.

I'm pretty sure it's a button whose knob was filed down. Note difference in colour and, therefore, the plating.

I have a button imitating a denarius of Trajan, so that would not be a first.

EDIT: Oops! I see that you knew it was a button! It is worthless because it would certainly not appeal to any button collectors in that condition. Even in perfect condition, I'd be surprised if it were worth very much at all.

Here are some examples of other "coin buttons". Looking at the prices, some of those sellers live in la-la land.
