There was a complete unopened ANS11 set on eBay for quite awhile in 2018-2019. It finally sold for about $100.
It was on on my want list, but I didn't purchase it because the 3 cereal cards aren't unique; they're just repeats from the ANS series just with C1, C2, ..... C9 designations. At the time I tried to search for how many were sold by Topps online, but have never found anything.
