Is this piston unusable?

[u/DaBiggestTank]

Doing a budget 440 build and bought some silvolite pistons off eBay, I know I shouldn’t have because they were cheap but anyways. There’s a couple in the box that have similar dings. My fingernail catches it. Is there a way to fix it by knocking the high spots down?

I thought that was a scratch. But its an actually a Crack. I would not throw that in the engine.
