I think this is a fake [解決]

All the details I can make out (and the photos are so-so) seem to match https://en.numista.com/catalogue/pieces13157.html

it is even 20mm in diameter. Obviously it isn't gold (or I've never seen gold turn green) So I am assuming it was a fake maybe with gold leaf or something at one time. I have not found any copper denominations that would match. So mostly looking for confirmation, but if someone finds an actual coin or token kudos!

There are many 19th century tokens (for games like whist) that were modeled after the "spade guinea".

Here's an example, and look in * Tokens * - United Kingdom - Counter Tokens for more.

​Indeed.
I have several different ones, with different dates

So does it matter much whether it is medal or coin alignment ? mine happens to be coin. If that is just chance, then I'll call it 'solved'
