How much is a 3D TV worth these days?

[Villain714]

Hello everyone. First off, thank you for taking the time to read my post.

I own a 2015 55 inch LG EF9500 3D/4K TV.
As we know, no new LG 3d TVs seem to be in the works as many of us im sure hoped for. That said, I feel like ive waited enough and feel it maybe time to part ways with 3d, and focus more on 4k and UHD content.

My question is, is there anyway I can value how much my TV is worth or is there anyone who can tell me what you think I could sell it for? Im having a really hard time figuring it out, as there is nothing online that I can find to go off by.

Thank you in advance for your replies.
