Can Anyone Tell Me What Is Wrong With This 1970 S Penny

I'm not seeing anything above the motto. On a tilted die one side of the coin will be struck up nice and 180 degrees out will be weak. The strong side is the left side of the coin. The weakness starts out at RUST and goes around to the 0. That corresponds to the NT around to AMERICA on the reverse. The usual weak strike of the STATES OF makes AMERICA even more weak. Silvio, more of a die adjustment error.

It's definitely not a greater as a grease strike wouldn't affect the rims. Not sure if it's a tapered planchet or perhaps PMD.

I wouldn't send it for a grade until you know what's actually causing it and if it's numismatically significant. I don't think it's a Greaser, as I said, because a Greaser wouldn't affect the rims, so it is intriguing. But grading is like $50 for error attribution, and you want to make sure the coin is valuable enough to justify that before sending it in (and you should get an expert opinion like Mike Diamond's to send in with it so they don't screw up the error designation as TPGs so often do).

As stated above, not worth slabbing. It's more of a nice find, and not a great find. I'd put it in a 2x2. But that's me I'm a collector. Eric, they're all over ebay, just if you want to pay for them.
