1964 Washington Quarter MS 67 Or 68?

It's definitely a proof strike, so agree the value would not justify grading.

Agree with all above--nice proof strike.

Quite clearly a proof.

Probably PF-67 or 68 but not worth the grading fees.

I agree with Bruce

Well it's Proof not MS. So of course it is well struck but hard to grade a proof from pictures.

most folks have no idea what it costs to grade a coin. it's crazy expensive now. this will give you an idea

consider the following for having a coin professionally graded
two reasons to slab
1. its a rare coin that needs authenticated and preserved
2. you are planning on selling the coin and the cost of acquisition plus the grading fee's would warrant it without chewing up all your profit

PCGS charges a minimum of $69 for a subscription other subscription levels include grading vouchers though so you could reduce these costs. add to the subscription cost, per coin grading cost which I think for this one might be $23, shipping & ins both ways (1-4 coins is $27 if the total value is under $1000)

NGC - economy grading tier is $22, plus $10 handling fee, plus $28 for shipping (1-5 coins).

ANACS grading would be $16 but there's a 5 coin minimum. Shipping would be $29-35.

CAC - $99 subscription ($50 grading credit), economy grading $15, gold $28, $40 shipping/handling/ins

i don't slab coins for these reasons especially the cost involved. I don't know why this is so popular today. just making the grading companies wealthy
