You can find these in these year 2016 and 2017 in the 30 dollar range graded 69 as long as they are the 50,000 mintage. I think it's worth it to pick up maybe one so you can see it close, but many of them have crazy prices with the lower mintages. I think the maxium mintage on these so far is only 50 thousand, but yeah I have seen the RP version on the bay with milk spots. I picked a few up recently, I admit, I became a little obsessed with these, but the prices and to many to collect knocked that itch back.
