The query will take you back at least 150 years, to a time when engraving was an immensely popular printmaking technique. So much so, in fact, that in the 19th century the term engraving was used to describe any reproductive print. Of course the invention of photography nearly wiped it out, but there was a time when the technique was so highly regarded that a Civil War engraving of Abraham Lincoln done after a Matthew Brady photograph was far more valuable than the original. Today, engraving is still used to print money because it is hard to counterfeit, and because it carries intrinsic prestige.https://dev.news.harvard.edu/gazette/wp-content/uploads/2001/04/03-cohn1-450-11.jpg
