Seller is calling it off center struck, but I wonder if that is correct. With little to no experience on errors, I hope dome of our illustrious members could chime in with their opinions.
Since the 84s do not have much of a rim, I would say it’s uncentered broadstrike, but yes the pros can tell you although you are a pro sir! I corrected my terminology.
Those are the sellers photos and no edge photos were included. For some reason, it just didn't/doesn't look right to me.
The design is off the coin, or basically off the coin (noticeable on the reverse, K= 2:00), so I'm leaning towards off center. However, if the coin has a larger diameter than 'normal', I'd change my mind to say broadstruck.
