Hi Val
No, SGC labeled mine correctly as W575-1 except they said they are handcut and they aren't. They have said they will take another look at them and I will probably let them at the National, in order to get rid of the "handcut" caveat on the flip. It's the W501s that I continually see listed as W575s that make me raise an eyebrow. Here are a few other W575-1s ...at least that is how I categorize them

. And I tried to clarify my statement above, a little bit.
