Really cool coin! Love it! However, please use pliers to mash the staples flat so that there is no danger of scratching other coins with it. I learned that the hard way as a very young collector back in a previous millennium. I do like the extra vertical staples so that it shows in the photos the rotation is not just a matter of your rotating the holder.
I believe it is to show us the degree of rotation, to give us a reference marker from obverse to reverse.
I remember when these started showing up a few years back. Started to quiet down now. I love how rotated the reverse why can’t we get that on a shield cent lol. These 2016’s struck thru rotated were found a lot. You’d see them on Facebook, eBay, coin forums. More then you’d see a penny with one
