Whoa, talk about timing...the butcher shop I visited last weekend also had pork coppa steaks in the case!
It's the oinky equivalent of a beef chuck eye steak. They might have a little bit of chew, but being from the shoulder they should also have a not-so-little bit of flavor. If they're not too thick I'd definitely grill them direct, and for the first time out I'd season with nothing more than salt and pepper.
