I probably don’t know what I’m talking about.
It’s not an official designation but to me they’re different from the ones with no lettering. I’ll put up some scans tonight. Got some Beckers too.
Also, the grading companies rarely label these correctly so the pop reports are not a measure of scarcity. And if you think you have a player run, check them again if you relied on a company’s holder. They’ll put -1-2 on anything (all I’ve seen have white paper).
