IMHO, and based on very limited experience - (I only advised my little daughter, on her collection of pet shop toys – I can’t compare this to greatest advisors for pottery collectors from sinking ship) - this how most old gold looks before its treated/cleaned, etc, etc... That’s assuming it comes from archeological digs in SEA! However, if your gold comes from archeological digs in UBS or CSFB, it might be nice and shiny, even after 1000yrs
