1991 DC comic book: is it worth money?

I really want to open it and read it. It’s still in the plastic package and I don’t want to decrease its value IF it’s worth something 😔

It’s in good condition, the spine of it has wear on it due to age but it’s never been read or even opened and is a holographic cover

This isn’t the only one I have. I have Batman comic books, some older some newer and I have some marvel Spider-Man comics. All never opened.
