1. Does anyone know what the metal octagon shaped coins are worth? i believe they are the 2014 editions
2. Does anyone know how to clean/restore the gold metal figures? Alot of the older ones seem to have/get alot of dark spots on their metal.. its not like when the paint comes off on the painted figures.. this almost seems more like a tarnish?
any info would be appreciated :) also, as always, still on the hunt for more metal figures :)
