I think your "coot" rack is cast iron, not wrought iron. Without labeling of any sort, I can't say whether it's from France or not, but it very well may be. Where are you located?
I'd give it a date of 1860-70s. Are there any condition issues? These things can be worth some coin; I'd check the internet for comparables. $1-$2K.
It's a beauty! Nice find!
