I happened to see a catalog of church supplies recently with communion cups chalices… they ranged from about $50 for a simple pewter or brass cup, maybe $200 for pewter/brass with a thin gold plating on the cup, all the way up to $5000 or more for a really nice decorative gold chalice with jewels and all.
Most priests I know do have one nice chalice that they received as a gift. If the Precious Blood is to be distributed to the faithful during Mass, the church usually has a collection of simpler matching cups. As a matter of practicality/cost I think pewter is pretty common these days, and although it can be attractive I don’t think it counts as a “noble” material. But from far away, it can be hard to tell if you’re looking at pewter vs. sterling silver, or brass vs. gold.
