Yep, it's a British jeton or card counter, often sold with decks of cards or other games of chance. It's made in the style of a British gold
spade guinea, but has obviously different legends. It could class as an "evasion" piece, but by the time these were made (early to mid 1800's - the "date" 1768 is false), the spade guinea was obsolete, replaced by the sovereign, so they wouldn't have fooled anybody.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
