Your coin appears to have a few contact marks that would limit the grade. The spots could cause a problem if a grading company saw them as residue left over from an old dip or cleaning. If they were seen as milk spots that develop on some proofs it wouldn't be a big problem and may be better to not try and conserve them. I am not good at guessing the grade on modern slightly impaired proofs. My dumb guess would be your coin will straight grade in the 64 to 65 range.
If your coin was a little better condition I would strongly suggest PCGS or NGC. You may want to look at ANACS as an option for this one and it may save you a few bucks in grading fees.
This coin was taken out of a proof set I had ordered directly from the usmint.gov website, so it's safe to say it has not been cleaned. So because of this, what you guys are calling "milk spotting" present on the coin, really makes the coin worthless? Even with such a strong RPM on it? Well if it's worthless I'm guessing there's no need to send it in for grading? That sucks I wanted to say thank you to everyone who took the time to help me understand what I was working with. I still considered this a win because I get to walk away with a little more knowledge about coins. Thanks Cecilia
"This coin was taken out of a proof set I had ordered directly from the usmint.gov website" So you ordered the proof set in 1968 and have had it ever since? "really makes the coin worthless?" "Well if it's worthless I'm guessing there's no need to send it in for grading? That sucks " Please re-read my prior comments "As far as value I would guess it would surprise you & most people here. My guess would also be that the coin is worth the cost of grading." "If they were seen as milk spots that develop on some proofs it wouldn't be a big problem"
@CeciliaS81 …Please re-read this entire post. Your coin is not worthless because it has a milk spot. It matches up as a Wexler RPM-002. Don’t give up hope. If I were you, I would highly consider, at the very least sending it to ANACS for grading and requesting RPM attribution gets on the label. Read the ANACS instructions carefully, find out what your total cost would be and then decide. Grading fee. RPM attribution fee. Secure shipping there and back. Mandatory versus voluntary insurance costs. And if you decide not, get it into a air tight capsule for protection. If you say no now, it doesn’t mean you can’t do it later on. Best of luck…JMHO…Spark
If it were mine, I’d get in touch with Wexler, send it off to him and then you’ll be forever enshrined with your name referenced. It’ll then be returned to you, along with I believe a letter indicating it’s attribution. Step 2, as I don’t think PCGS or NGC would attribute the rpm on the holder as it’s not currently recognized, ANACS would and likely label as the Discovery Coin. Step 3, promote it yourself, then put it on Ebay with a fixed price of your choosing. As it’s not required for registry sets, it’s somewhat limited, but the hardcore collectors would definitely want it. Ex post facto, hocus pokus and I’d value it in and around $3500-$5000 GC would be a valid venue, If they would agree to feature it….that would take a phone call. If not, then you’d be better off selling it yourself. Years back in a similar situation my coin went for near 5K, whereas a higher graded example found later went off, sold at GC for $2K in a true auction. True auctions with a limited window do not result in max value as it’s necessarily limited by whomever just so happens to see it before the window closes. Plus, who’s looking for 0 pop coins. It’s also possible that because the big 2 won’t attribute that the interest is thus low, that possibly other examples exist in graded form just without the attribution. I’ve been away from things for awhile fwiw.
