moly is a facing on a ring, not what the ring is. A ductile iron or steel ring can also be a moly ring. I'm guessing you just want a cheap set of rings though (cast rings), for the extra $15 the moly facing is worth it IMO. Other than the little extra cost there's no downside to moly and it tends to seal better and be a little more durable.
