Is the 1952-D Franklin silver half really rare in full bell lines

I was reading on some forums that the 1952-d franklin half is really hard to acquire in higher grade conditions.I found this one and  was thinking thinking it might be a higher grade,compared to the others. do you think it will be expensive since other websites are saying th bell lines are hard to get on this date.or will be acquiring it be easy.

I havent been collecting the half dollars,this one made me think about starting.

1952 d is common. Book value is ms 60= $5.20  Ms 65= $130   ms 65+ =  $450

You would have to get it professionally graded.

it ended too early in the morning.I missed it.would have been a pretty good deal.
