This coin is part of 1927 proof set I bought from USA many years ago. NGC graded is Proof Details ( OBS Cleaned) a bit crazy as the 1/2 crown of the set got graded PF65 and all the rest of the set got graded PF62 - PF64. Why single out this one being cleaned ??
Still you win some and lose some with these US grading companies I suppose. Thanks
