Forgotten

[Truerenigma]

Hi starstruck,
Not every poems needs a meter, but the line breaks may need some work. A few other nits.

Forgotten,
Like the way the sky forgets the sun at 1 AM, the sky doesn't forget. The moon remembers
You forgot me.

I was replaced.
You traded in your coal for a diamond,
Leaving it to fade into the wind without a trace. "without a trace" is a little week, and the rhyme isn't really worth it. "Leaving it to fade in the wind is stronger, but has nothing to do with diamonds or coal.
Just like you left me.

What once was a treasure
Is now merely rubbish
That you tossed away.
Just like you threw me away. this whole stanza is cliche

Forgotten,
Like the penny left in the pocket of an old pair of jeans, this I liked. But it could be simplified. In fact, it's the whole poem for me. You could actually have a decent poem if you just built around this analogy
You forgot me.

The Penny in Your Pocket/ Forgotten:

Forgotten like the penny in your jeans
that's left to bang against the dryer walls,
you left me there. Now no one can see my sheen
of copper gleam. I'm tumbling through the seams
of your old things, remember those old dreams?
I'm clinking in your pocket but my call's
forgotten; like the penny in your jeans,
that's left to bang against the dryer walls.
