I doubt the gold pieces are brass as there would be no need for a finishing coating. They're probably the same as the silver pieces ( Pewter or something like that) but painted or gilded. You could probably buff the silver ones up if needed but you'd have to find out what the gold pieces are coated with and re-do. You'd need to do some research for that.
Metal chess set - How to restore?

Appreciate the response! I think you're right, I'll have to figure out what the finish is and if there is someone or some way to re-finsish/repair.
Hi, I'm wondering if anyone might have some advice...
I have a metal Italfama chess set from around 1999 (see pics). The pieces are metal (brass?) as is the board I assume. The board itself has tarnish/oxidation, and I'm actually not sure if it's Italfama brand or not as there is no label. In any case, I am more interested in fixing the pieces. The gold pieces are marked up with scratches/scrapes, and I am wondering what, if anything, I can do to restore them. Seems like the gold colouring may be some sort of finish that has been scraped off while the silver pieces are just unfinished polished brass or other metal. The silver pieces look great and do have a slight patina on some pieces that I don't mind at all. The gold, however, need some work. Just wondering if anyone has advice on how to clean up/fix the gold pieces. Also, is there a way to tell if they are brass or a different metal? Thanks in advance!
