Hey guys picked up this old looking pewter sugar and creamer set. I know nothing about pewter except for the fact some pieces are collectible and valuable. These are definitely far from that however they were $4.99 for the set and I thought why not! How old do you think these are? 1940s? Earlier? I'm trying to learn about pewter and I know at least Flintlock collects pewter here! Looking forward to hearing from anyone who knows more about this stuff than I do! Finally how do you polish pewter? Can you use silver polish or absolutely not haha?
