I was through my Team Rocket Returns reverse holos (as one does on a Thursday night) and I noticed that my Dark Steelix has a swirl within the typical reverse holo pattern. I went through other stamped rares that are holos and didn’t notice any other swirls or cosmos holo patterns. I also didn’t have any luck researching online.
Is this just a rare occurrence or some sort of misprint?
This is not a rare occurrence or a misprint.
All TRR reverse holos have both the reverse holo pattern (energy symbols, stamp) and a normal cosmos holo pattern visible. Swirls can be found on any of the reverse holos. Aren’t they beautiful? 
Not too rare, though possibly hard to distinguish with everything else going on in the holo. I have a few. I’ll look through anther time, as I’m curious to know how frequent mine are. I chose to look at my Arita set tonight. 
Great placement on that steelix tho! I’m definitely jealous.
they’re definitely nice. too bad about the borders
