Do I have two detached wing mexican proof libertads?

So the original coin that brought this variety to light was a 2oz 2015 silver proof mexican libertad and had something to do with the state of the die polish I believe. You can see the article here: http://world.mintnewsblog.com/2017/03/libertad-varieties/ From the very few posts and articles on it, it seems like most people are only looking at their 2015 2oz proofs for this variety. However I looked at my 2013 five coin set and found what seems to be a similar if not the same variety in my 1/4oz and my 1/20th oz. Can anyone give any insight as to if this is what it seems to be and if they are worth it to send in for grading and what would be an average price for these pieces. Thanks!
