I ran across this on ebay. I've never seen one before. Based on the photos I'd say it's quarter sized or a bit smaller. The obverse looks copied from a Seated Dollar and It looks die struck.
Likely a counterfeit from aliexpress.com or similar.
I don't see this exact item on aliexpress at the moment,
but the date style looks like an aliexpress type product.https://www.google.com/search?q=site:aliexpress.com+1868+seated+liberty+coin
An egregiously ignorant COUNTERFEIT, but a counterfeit nevertheless.
Some people will say that it cannot be a counterfeit because the U.S. Mint never made such a coin. They will be wrong.
Quite the forehead there.

Counterfeit beyond a reasonable doubt. Likely - as stated above - from aliexpress. Cheers, RickO
