What's the grade of this coin?

VG-F. The coin is worn and the planchet has some really difficult toning.

That's a bit harsh Bam, it's certainly better than VG.  I'd go for around F

Thanks guys! I expected it to be something around VG to F. With your opinion I'm sure it is.

I think an F grade is fair since all the detail is present, it's just had some heavy wear. If it was mine I would be a little concerned about the green toning and I would be tempted to conserve it with a little isopropyl alcohol and a cotton bud to make sure it doesn't get any worse.
