Here is a used hammered copper bowl, from an unknown maker.  It also has a finely hammered rim, and an interior that appears to be covered in a sealant, producing a darker, cloudier appearance.  

No maker's mark, country of origin, or date.  If anyone can shed light on this piece, please let me know. 

7.75" wide, 3.5" tall, with a 5.5" rim.  Weighs 1.5 pounds.  

Condition: Partially cleaned exterior, but still producing a relatively even light patina. There is a 1" diagonal dent near the top.  As mentioned, the interior looks to be sealed, with a darker, cloudier appearance.    
  
Please see photos.

I will be listing other pieces of pottery in the coming days, and am always happy to combine shipping--just let me know. I start all my listings as true $0.99 auctions. Good luck bidding!
