Commonly duped things

[BGAFgammer]

I know that Hr's are commonly duped however what are some of the other things that might be duped???? I heard something about Baal eyes being duped is this true? Also I was reading a trade forum post and it said something about doing a dupe check to make sure that it was legit. Can and or how is this done???

Baal's eyes are not commonly duped, but there is an exploit that makes them extremely easy to get.

There is no way to tell if an item is duped.

Any expensive item with perfect stats is likely to be a dupe.
