My guess is 58 due to the wear on the eagle, however it could just be a very weak strike. It would be quite odd to have a weak strike on the obverse and reverse, but I'm no expert. If it's a weak strike, it could go 66.
It's... hehehe... Striking. The fields are beautiful.
The die crack across the top ought to be a dead giveaway for a VAM for one of our experts.
