Metalwork Wrought Iron Rose Sculpture

I am curious if anyone can help me place a value on this beautiful metalwork wrought iron rose sculpture? I found it in a thrift store.

I believe that the green is patina and not paint. I found one similar on the internet that was new and worth several hundred dollars.

I'm thinking this one is antique.

If you no anything about this type of thing, I would love to hear what you think.
