The coins were minted in honor of the 1976 Summer Olympics held in Montreal, Canada. The set also comes with a CANADA Certificate of Authenticity, providing proof of the set's origin and legitimacy. This set is a rare and valuable piece for any collector interested in Canadian or Olympic memorabilia, and it is sure to be a treasured addition to any collection. The 10th picture is the only one that doesn't have the certificate of authenticity, all others have them and are double sided one side is English the other side is French I believe.
