Thats cracking crypto coin slabs (with uniquely identifiable addresses), and resubmitting them ? (so ANACS dont keep a record of the addresses they have graded ?)
Correct. You crack the slab on your own and resubmit the raw coin.
If you pay for verification service (which you should) then the first bits may get placed on the slab, in which case they would almost certainly have some kind of record of it when you send it in a second time.
They may, or they may not. I don't know what information ANACS keeps in their database, whether they'll record the firstbits or not. But either way it doesn't matter. Why does ANACS (or any of them) care if the coin was submitted 1 time or 100 times? They'll grade it 100 times, and give you the same grade 100 times, or not. They still get paid 100 times...
Also, while ANACS the company might keep a record, chances are the graders won't remember a particular coin or address unless it's particularly memorable (1BTC1234 for example). Remember there's many graders, each coin sees usually at least 2, as many as 5, and they go through so many coins they won't remember seeing a coin again unless it's back the same or next day to the same exact grader. A grader may see well over a hundred coins in a single day (at our coin service level), they usually take less than a minute for each coin then pass it onto the next grader for their input. The graders keep notes only enough to make their grade scores, and verify the bits are correct. The labels are done by a different department completely, who then enter whatever info is needed into the computer systems.
Figure this - suppose you had the coin graded, then you sell it. The next person doesn't like slabs and cracks it out and puts it in an airtite or an album (don't laugh, this happens all the time with "regular" coins, there are people so anti-slab they'll crack them and "free them" from the "plastic jail" they are in). Then he sells it to someone else, who wants it graded. They send it in and it gets graded again, getting the same grade. ANACS doesn't really know if it's the same person submitting the same coin or not (could be your local coin dealer doing it for you, etc), and again, probably doesn't care.
The major risk of removing the coins from their slabs is that once you do this, you are loosing ANACS's guarantee that their grade is accurate. If you submit a coin as a crossover to ANACS and if they come back with a lower grade then you will be compensated for their original error. This means the worse case scenario that will happen when you resubmit a coin is that it gets the same grade, and a better case scenario is that it's grade gets bumped up one or two notches.
For anyone looking to keep the coin in their collection, I'd agree with you, it generally doesn't make much sense to crack and resubmit - just buy the higher grade in the first place. That is, unless it's a really rare expensive coin which you can't afford the higher grade. This is common - I've cracked coins when the difference in the next grade up is several hundred dollars, hoping I've judged it correctly and it will grade higher and I don't have to spend the difference. Many people do.
But, anyone cracking a slab isn't really concerned about the guarantee. They're purposely gambling to try to get that higher grade. The guarantee is worthless to them at that point. If they are sure it will grade better they'll do it and if it works out it's usually very rewarding when sold.
Agreed it has worked well for me in the past. I still am a firm believer in cracking the slabs before I submit though.
Me as well. I've successfully cracked and resubmitted many coins. One time turned a $300 coin into a $1500 coin after it came back a half grade higher.
I always crack myself and re-submit raw, and I recommend it to folks instead of sending it still in the slab. However, it's extremely easy to damage a coin doing it yourself, so it takes practice - do it on a cheap ass coin first...
. I've caught the coin on a jagged piece of the slab a few times, sometimes getting lucky and other times paying for it dearly. Just gotta be patient and careful...
