Anyone Familiar With SGC Grading?

We'll get to that question in a minute - first some PC adds. Over the past month or two I've spent a lot of time searching for, purchasing, and showcasing the Pirates gold refractors. While the gold has been flowing in and that's my top collecting priority, I'm also constantly on the hunt for black refractors as well.

This came to me through through a recent PWE swap through TCDB. I must say, as a newcomer I'm really enjoying trading on the site. Even though I'm not a set builder, I'm a team collector, and I'm finding that it's a really great way to turn unwanted cards into wanted Pirates cards. The "cost" of acquiring this card was a Miguel Andujar base rookie, a 2018 Mike Trout base card and a few other commons. My trade partner also sent me two Bryan Reynolds rookie cards and another parallel that I'll highlight in a future post. This card would run me $5-$10 and chances are I would have eventually bought it - so this a big win.

I wish someone had this available for trade too, but the black refractor on the left is my most recent eBay pickup. Two weeks ago I spotlighted the same card but that was the gold refractor (pictured right). This is the first "black and gold" combination I've acquired.

On to my SGC question.

I've been keeping my eye out for this card for a while. It's been the most difficult component of the 2013 Topps Chrome black refractor Pirates team set, which consists of four other cards - Andrew McCutchen, Russell Martin, Startling Marte, and Justin Wilson. I don't own that many graded cards. Maybe 12-15 total - but all of the ones that I own are either from BGS or PSA. In fact, I'd never even heard of SGC until I saw this card, so needless to say this is the first SGC in my collection. I wasn't searching for a graded copy. In fact, if I had my pick I would prefer this card raw, but the price on the card was the same as the raw cards have gone for. So I pulled the trigger. The condition of the card isn't of terrible importance to me in this case.

I am curious, though. I see that it is "Mint" and looks to have received a grade of 9 for *something*, but also a grade of 96. Is that a scale of 1-100? If so, what's the 9 under Mint for?

Has anyone reading ever graded with SGC? Any and all advice is appreciated...
