What are the chances of a Canadian vending machine thinking a UK 5p is 10¢?

Question

The 10¢ is just a little bit thinner than the 5p but they're the same size apart from that.

I'm guessing it wouldn't recognise it as anything and eject it but I've known some vending machines to take amusement park tokens for money.

Answer 1

Most likely reject it.  Especially that thinner 10 cents.  But it's worth more, so not sure why you would want to.
