Resubmitting Coins To Be Regraded

It's estimated that as much as 75% of the graded population of some issues is from resubmissions - for instance, PCGS has graded 100 of them but there's really only 25, being submitted over and over again. If the coin is worth enough in a higher grade, people will submit it 25 times in the hopes of catching that one grader having a bad day who upgrades it. That's how common resubmissions are, to answer your question.

If anything, a submission results in a downgrade more often than an upgrade, and the number of times the same coin will come back at the same grade outnumbers the other possibilities combined. You're talking about an extremely speculative process, with a poor rate of return.

I can't add much to what Dave stated except that the big crackdown on Morgan grading by PCGS, NGC, and ANACS starting a couple years ago has lead to even lower probabilities that a Morgan in a top TPG slab would keep its grade if cracked out and resubmitted. And the persistent urban legend that older PCGS "green label" slabs were graded more conservatively than these days and could or would be upgraded if resubmitted is absolutely false. If anything, such older slabs are most likely to be downgraded. Yet, green label PCGS slabs still bring in premium values due to this legend. If one has a decent grade in a top TPG slab, stick with it and don't try to resubmit it in the hopes it will regrade upward. It ain't gonna happen.

Your better bet (although very risky) is to take raw coins and submit them. If you find a good one that you (with your new, improved grading skills which you learned, at least partially, here ) you think would grade higher than what you can buy it for, then you might have something. But I have to agree with the gurus on here who said don't do it. Your skills as a grader won't be as good as the TPG's, and something you don't know to look for may be obvious to them, which put you at a big disadvantage.

I have some coins I bought from ebay graded by SGS(They've all been graded MS 70 or PR70) but I would like to get them graded by another company as I think most SGS coins are over-graded. Now the question is whats the best grading company to resubmit coins?

Knowing that SGS coins are overgraded is a good start.

You'll be lucky to see even one MS65 from those MS70's. I will say, the guy gets nice coins - I haven't about heard a whole lot about SGS coins ending up bodybagged, like some of the other alphabet graders - he just vastly overgrades them.

The "best" company to resubmit to varies by opinion between NGC and PCGS. PCGS slabs usually carry a premium over the others in the market. I'd sooner send a Modern to PCGS than NGC, because they're tighter with the grading, but that may not be your aim.

Of course, your coins have to come out of the SGS slabs before grading, but I figure you already know that. What types of coins are we talking about here?

I was reading I think it was either PCGS or NGC and all you have to do is send the coin in it's holder with a crossover grade request, and you have to state that you want it graded a certian grade or better for the coin to be taken out of the slab and put in a new slab.
In response to Dave's question, there mostly Modern coins-between 1965 and now.

I would consider it the equivalent of numismatic suicide to submit a coin for crossover to PCGS in an SGS slab. Such is SGS' reputation in the real world.

One other comment on the original post regards the subjectivity of the grading process, something which is very commonly stated in ebay auctions for raw coins and non-rated third party grading services (CCGS, NTC, NNC, PCS, ANI, etc., etc a hundred times). The seller invariably makes this comment, then applies his own grade which is also invariably several grades too high.

True, grading is subjective to a degree. However, the established standards for grades such as Photograde and ANA (PCGS also defines its own grades) are fairly specific and the top TPGs (ANACS, PCGS, NGC, and ICG) adhere to these standards as closely as humanly possible. Their grades will seldom vary more than one grade above or below from each other for any particular coin. Further, only the four top TPGs will guarantee their grades and back their grades with money back if their assigned grade proves to be mistaken. With the boiler room grading companies, there is nothing more than a guarantee of authenticity and most won't even guarantee this. The use of the word "subjective" for the basement slabbers should be substituted by "arbitrary" with assigned grades differing from the standards by as much as 11 grades. Of course, none of these latter slabbers never, ever grade a coin too low.

Ouch, TLS. That's especially grating considering what James Taylor said about reholdering:
