2016 First Spouse Bronze Medal Set

First post and at some point I will post about my collection and my idiosyncrasies of collecting that I seem to be different about. I noticed yesterday when I went to the US Mint site to check if the SL gold quarter was still available, that the 2016 First Spouse bronze sets are also listed as "unavailable" 1 week after release. I began buying 4 of these (1 for myself and 1 for each of my children)from the mint in 2007 after deciding I could never afford to buy the gold versions of these designs. 2007 was acquired for Christmas and I did the same in 2008, but ended up with the same 2007 sets again. I almost returned them, but didn't, and got out of sequence with buying for each Christmas. Started back up and have a collection of 4 of each year except 2013 which sold out early and I bought one for too much money on ePay. Set up for "Product Enrollment" for both these and Kennedy 1/2 dollar roll boxes and so received my 2016's yesterday. If they are already sold out, may these also skyrocket in price like the 2013's. I have never been able to find any mintage data for any year. Can anyone point me in the right direction? As a side note, I was very lucky I never sent the 2nd set of 2007's back because several years later I learned about the error of the wrong Adam's reverse and these last 4 are all of the error version. Any help would be appreciated.
