Charles III, on the right of the crown, wore it; it has been owned since 1540 (remake).
Value Estimate: $5–$10 million*
The importance of the Crown of Scotland to Scottish history cannot be overstated, as it is the oldest remaining crown in the British Isles. The Crown was used to coronate Scottish monarchs after Scottish monarchs since it was first used in 1503. Since Robert the Bruce originally wore the circlet at the base of the crown, it dates to 1306.

In 1540, the Crown was recreated using pure silver and gold. Forty-three jewels and 69 Scottish freshwater pearls embellish it in addition. The pearls alone can be valued at $207,000 or more.
