Not related to grading, but the rate at which PSA is mislabeling US issue vintage cards as Venezuelan issue, is going up. I've been collecting and grading Topps Venezuelan cards since 2019.
Thankfully I can email errors that appear on Ebay to my rep and they fix the pop report on the backend, but it's still floating around in the wild in a wrong flip.
And some of these are not small errors. This Mantle is a US issue Topps card, comps around $400. The Venezuelan Topps version in a PSA 3 is worth 10x.
