Coin To Identify Possibly Roman?

Definitely not ancient, because the bronze still seems "fresh" with no real patina.

My best guess is a jeton (counting token) or gaming piece. I can't quite make out the legend; can you post a transcript of it? Obverse looks like "NINER" and then upside down triangle A?

Jetons were made to help accountants do their jobs, even if their literacy and/or math skills were extremely poor. They were cheap, coin-like tokens, usually with some sort of design, either modeled after a real coin, or just a fantasty design. They fell out of use in the very early 1900s, where they were used as manipulatives to teach arithmetic to school children.

Jetons are usually a bit larger than a quarter, some have Emporers images/names/coat of arms or other religious designs. This has a very modern depiction of roman centurion with modern English "miner". The rear is design and gobblygook. If it is quarter size I would venture it is an arcade token from the 20th century.

It is a Nuremberg jeton, struck by Joseph Lauer. The obverse is Minerva (obverse legend MINER-VA), Roman goddess of wisdom. Reverse legend is the maker's name IOH:LAUER and the descriptor: RECH:PFE, which is short for the German word "rechenpfennig", which means "counting token". The star pattern on the reverse is purely decorative.

It probably dates from the late 1700s or early 1800s. Jetons at this time period were often sold in bulk with packs of cards.
