1972 S Jefferson Nickel (Proof) FS

To get the right grade you need to take it out of the holder, but I would say PF 67

Looks like a couple marks so looks like this one would be PF-66 at best. Only worth a couple bucks.

I'll say PR-66.

High grade coins graded by PCGS always sell for more than a raw, ungraded coin.

The ANACS-graded PF-67 that sold at Heritage several years ago for $4300 was a dramatic double-struck error coin. A typical 72-S PCGS graded PR-67 sells for about $10, and less if not in a holder.

Here's the record auction coin, obviously nothing like a typical proof nickel.

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 but they are still high. 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
