I think it was the same card that someone bought and flipped as I remember. It just vanished after that and never saw another glowie since. I have seen some no #'s even some PSA 10's , so I'm going to guess if there were 50 no #'s there might be a handful only of the glow's . Just my thought
There was one sale not mentioned if my memory serves me correctly, so the numbers are very low for sure - 5 or less. However, it takes a keen eye to tell if you have a glow one or not! These are case hits, so maybe if you buy a case you are more aware of what is in the case than a kid buying packs at Walmart, but i'm thinking a few are still in the wild.
I literally placed all my minis in the sunshine to help me find the glow ones. Very easy to miss in my opinion.
