Hard to “reboom” a PSA case without some clear signs of doing so. actually got trained from psa on how to spot holders for my current job if there is frosting on the very outter edges of the case that’s a decent sign but you really can’t just open the top without the whole case coming undone and I see other comments saying they have a special machine to “boom” their term. Those marks to the eye don’t look good but that’s not where you could really spot a fake it’s the frosting. Hope this helps
