This is the most detailed / cool antique French key that I have ever seen. That might explain why the asking price is $1,250.
Unfortunately, this key is outside my price range.These auction online is for an antique french key from 18th century. The key has a spade shank (rare) and an unusual cut double bit. The collar is ornate. Measure 4,2" long. Weight : 200 grs - eBay
Update: This key sold with a 'best bid' of $875 (Plus $9.05 shipping).
