If you want to get it graded, you can send it to either of these places:
https://www.psacard.com/
https://gosgc.com/
The result is going to be spending money for one of them to tell you that it has questionable authenticity (their phrasing for fake/modern/fantasy piece). They will send it back to you not enclosed in one of their holders so you will have the card just as you have it now.
It is certainly your call on paying the money for this, and I understand some hesitancy of trusting a bunch of people on the internet with whom you have never interacted, so I can see some motivation for wanting to send it in. I would ask that you come back here to post the results when they send the card back.
