Those certainly look like tiny frogs!

However, I'm having a problem with scale. I have never seen British coins in person so I don't know how they size up to Canadian or American coins.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
