"hard green" patina -- example?

Is this a good example of a "hard green" patina?
If not, can someone post a good example.




Also how much of a premium (if any) should one expect to pay for such toning?

It looks nice, but it does look like there is some exposed metal too. What does the obv. look like?

 

thanks mat ... so i have to watch out for faked green (AT) too

randy, i just now added (posted) the obv. in the OP

 

Thats pretty cool.

 

This looks better than average. You might find some interest in my grading pages but they were posted before slabs and the grading system they use and they won't help you grade with their systems. I'm not sure how you would tell a real vs. fake patina after a coin is slabbed but the photo looks good.

That's some Funky Green Patina!

 

Heres a couple nice green ones of mine, and one that would have been nice.

 

Good god. Flashbacks to the late 80s.

I found a nice 1882 indian head cent with a beautiful strong green patina. I think it looks amazing but i dont know much about toning. Will that inhance or decrease the value. 9its not like bumby crumbly corroded stuff).

 

Photos would help

 

What you are referring to is probably verdigris, or the green stuff that shows when copper oxidizes.... it is actually damaging to a coin if not reversed quickly....

 

Not necessarily. I have certainly seen cents with the "hard green patina" that the OP is looking for. I personally find these to be attractive. But as Zach demonstrated, US collectors will quickly assume its verdigris and run away screaming. So for a US coin it detracts value.
