I agree with this. Chrome isn't automatically a mirror finish when applied, if you have seen a rough casting chromed you know what I mean.
A mirror finish chromed item is polished first and then chromed. I suspect this is why the wheel is engraved polish and chrome.
Copper would be used as a plating underneath the nickel and chrome platings.
