How much is it worth? How much will it be worth after getting graded? Grading fees, return postage, insurance I am told can run $30. While it is a nice coin, there's really no reason to put another $30 into it. You can encapsulate it yourself, or just use a 2x2 coin flip.
Certainly is a nice half. I agree fully with @Michael K. An 81-P is a common date. Certainly protect the half with an inexpensive flip or something similar. But don’t go through the expense of grading unless the half holds some personal significance to you.
The PCGS price app says that coin would need to grade MS67 to be worth grading (goes from 90 in 66 to $425 in 67). They sell for much less than guide typically. Your example is nice, but I do not believe it would not make a 67. You example is nice, but I would not spend money slabbing it. Matt
One of the nicest Kennedy's I've seen raw in a long time. It's a common date and I don't think it would grade high enough to cover the grading cost. Protect it yourself. Several options are available.
I like that part. A good chunk of this whole hobby is turning a profit with grading (and it's ok. I get it) but i also encourage what you just said. If it has some personal significance to you, why not? It's $30 to protect it in just about the best way that you can. I do realize that this can be accomplished with some cheaper do it yourself slabbing but you don't' get a professional opinion on the grade. Good call out @Randy Abercrombie !
