Injection molding is not suitable for casting silver because of high temp. Injection molding is widely used today and was used during TR for aluminum like alloys and alloys with lower melting point, so 600 C and lower.

Back to Antonio's pics. He made systemic mistake. Guy made copy of ring with defect. He copied not only ring pattern but all defects too. So he compares defect with copy of very same defect.

If somebody want to play science - density is keyword. Measuring density and comparing with other will not destroy or damage ring and it will give measurable results.

There are less original rings than you think, much less...
