Turns out one of my purchases was most likely a trimmed card, but luckily the seller was very accommodating and promptly refunded me.
Here is a link - I compared it to many other Hornsby R315s on VCP, and I think SGC dropped the ball on the numerical grade. It looks quite short top to bottom, with the trim likely on the top edge. I'm mad at myself for not researching and catching this before I bought it.
