1968-S Quarter - RPM On PR-69?

I feel the real value is more in the graded coin. The mint mark issue is not a premium for your coin. You might check the PCGS site to see if they give a value for your coin? There were a lot of high grade proof coins in the 1960's. So you would need a price for that year on this. BU coins some years don't grade very high, some proof coins do have higher grades.

WTG,
Congrats on a great find!

At the risk of seeming overly needy, I need more advice here if some of you are willing to provide. I think the right thing to do is to send it to PCGS to have the variety affixed. For some reason, I'm nervous about that. I sent them an email asking whether or not it could be downgraded in the process, and I got a rather generic response back basically saying "we can't guarantee that."

So, my questions are around submitting (I'm already a PCGS member, though I haven't submitted anything yet). It seems like I should submit as a "reholder" with the "variety attrib" selected... identifying as an RPM FS-501. Questions are:

1. Does that sound right?
2. Is there a risk of downgrading because of the RPM?
3. What's the best way to send the slab? USPS Priority with the form and insurance?

I would just hate to get it back with the attrib but with a grade change to 68. Any advice would be most appreciated. I feel like I have something cool here, and I don't want to screw it up. Thanks!

PCGS only uses the FS numbers for the grading purposes, which also costs more for this service. Anacs will graded with other attributors numbers. (even coppercoins numbers will also work) So you would need to see if it matches the FS numbers. Then you might have a chance.
They will tell you how to send your coin.
I would make sure you have a match before you submit your coin. It is always safe in the holder you have. If you have to send it back to them, they will probably ask you to remove the coin from the holder. (which I would not do) IMOHO

UPDATE: Just got it back from PCGS with the RPM 501 designation affixed (yay). My first cool discovery. It's now in the pop report (the only PR69 for the 1968s) - no value attached. I assume it has to get sold before it gets a value? I was hoping they'd throw out an estimation, but to no avail. Do you guys know how that's done? Do they track sales and publish the latest value based on that? I'm interested to learn about the process. (I have no intention of selling it, regardless of value)

Thanks for everyone's support. I'm so addicted to reading posts in this community.

I told you that you had a very rare proof variety in your possession!
Like I said, the coin is a real game changer for the series, although wouldn't be considered the "Discovery Coin" as Coop suggested since it's not the first known example of that variety.
Who cares!
You now have in your possession something MUCH better, the finest known example of that variety giving it the prestigious title of TOP POP 1/0 with none finer!
And being that it is attributed in a PCGS slab, along with its very low population figures, (only a handful attributed across all grades) it makes it HIGHLY DESIRABLE to the high end Registry set collectors which could easily result in a an all out bidding war if you were to list it in one of Heritages high end, well publicized rare coin auctions they have every year!
Personally I think your setting on a small fortune, I'd put a conservative estimate on it of close to 5 figures if not more.
Just go look up the value of other top pop 1/0 variety coins, it's quite impressive!
Congrats, on the Cherrypick of a lifetime and I'm so glad you followed through and resubmitted the coin!!
WOW! Hell, I'm happy for you!
