Spanish Doubloon Though It Is In English?

Something found in cereal boxes.

If there was any room for doubt initially, why would Spain put a description of the coin on the back in English and French, the language of their enemies?

Sorry, I should have been more clear, or I made too many assumptions. To determine authenticity, you need a basic starting point. It needs to look like the original. In this case, you would not even need to look at an original, as a spanish coin would not have used those languages. So even if you do not have a book with you, there are clues that something is not right. I only mention this in case something else like this comes your way.

Oriole,

I am not really sure what you're asking, but if you are wondering about the authenticity of the token or any value it might have, unfortunately it is a modern imitation piece for children.

There are many ways to tell it is fake, the most obvious being that any Spanish doubloon is equivalent to two escudos, meaning it would by definition have to be made of gold. This coin is made of a low value base metal.
