That ice is getting thinner every minute. Do you vaguely remember what this topic is about? Rick's initial message was about the RCM's multi-ply technology. Also see this brochure: https://www.mint.ca/store/dyn/PDFs/MRC115003M_Brochure_Multiply_En_Client.pdf Christian
Because of demand and production quantities. Reliefs have been lowered to accommodate high speed presses and minimize die production. Metal and Alloy costs are also significantly higher than they were "100 Years Ago". And let's get realistic here, if the US Mint figured out a way of making coins that looked like what was produced 100 years ago, public, both collector and non collector, interest would not change. A prime example is the 2009 cents which revisited not only the higher relief but also the Copper Alloy. None of those coins have any significant interests much less premiums associated with them. Why? Simple. Regardless of what they do they'll still be producing a "Modern coin" but the hundreds of millions if not billions. Nobody wants what everybody already has.
