Solve this for me please:

Can you tell me if these are CND or American cards?
1. They are being sold by a CND.
2. They are listed on ebay.ca
3. The description does not state either way if they are U.S. or Canadian backers, but does state to email the seller if you have any questions.
So, assume you collect these, and see them with 5-10 mins left in the bidding time.
What would you do if you
only collected
U.S. cards and you saw these?
Thanks,
Mike
