Do we trust them now?

Any new grading service has to overcome being put in the same group as the ones that aren't even genarally consistent. All the big 3 make mistakes, but over thousands of cards are generally right about trimming, and generally consistent on the grade.

But there's a bunch of grading services that haven't measured up in one way or another. I think I read somewhere that PSA had a collection or database of about 2000 other grading companies. Some probably found it wasn't all that easy, some probably had a poor business model from the start, and others couldn't get it right. The worst of them intentionally never get it right.
Like the "graded" spaulding guide pages one guy sells on Ebay, a screwdown holder and a sticker don;t make a grading company.

I've seen a few others that never seem to grade anything as less than an 8. (Probably actually only 9 or 10, but I'm going easy since I don't look at many modern cards)

So yeah, anyone new has to establish themselves as reliable before their work will be generally accepted.
