If you are nervous about grading it, then why not use the “Ludkins” grading service. They will take care of it for you and do it right. It’s the easiest way to grade a card without being a member. I highly recommend it as the most practical method if you are nervous.
I’m sure perhaps quite a few people here use ludkins, as mentioned in the comment I’m quoting. I’m not sure where you’re from obviously haha but Charlie, who heads ludkins u.s., is a super super cool dude that is very professional and does a magnificent job with his grading services. And he’s just generally a pokemon card aficionado too. I have sent in 200+ cards in 4 different submissions through him, so I can vouch for the quality of the service, you won’t be disappointed going that route. But just to resound what others have said, for more money you aught to grade it if you have the patience to wait potentially several weeks longer. I hope this helps!
