QUESTION pinopolis cutout pin question

it is silverWhat color is the back of the Ariel?
the back of mine is definitely silver after seeing that photo but it says le 500 on the back so its a le 100 chaser?
I'm guessing Bronze is actually Antique Gold now? I posted pics of mine but haven't gotten an answer as to which variation they are...
I looked at the picture you posted and couldn't tell the difference between antique gold/ bronze and "regular" gold. I wanted to ask if there were any differences on the front due to differences in the base metal. Did you notice any?
