About the engraving Hapur, I can make it appear new, old, scratched, worn, very worn, with patina, without patina.... Just invest some money, find the right jewellers and engravers and everything is possible.
Again: let the pictures talk themselves. If we want discuss about theories without any foundation we will not move of a single step. If we want to discuss the real evidences maybe we can go on. I think I showed many here, and no one can confute them with other proofs. Of course we can close our eyes and, as a blind, go on.
I thought me too these rings were die struck, but everything is screaming the contrary and I found NO ONLY ONE proof to support what I thought.
BTW: just a couple of shots of a worn engraving on a cast fake ring.
