Ok from doing research the 2015-16 Set was released in Aug 26, 2015. It has 50 card base set, Each box contains 86 cards—50 base, a complete 22-card set of Winning Standard jersey cards, 10 autograph cards and an additional four memorabilia cards.
I would put it under the 2015-16 year. It is different than the 2013-14 Team Canada set. This is the Master Collection and as you mentioned it is on thicker stock and it is serial numbers.
Trying to acquire one card for every for every set, insert, parralle, minor, euro, team issue, oddball etc sets produced for Hockey. Been an interesting project.
