coin slab manufacturers

alll: Can anyone provide or point me to resources that can identify the various companies that manufacture the slabs that PCGS, NGC,
ANACAS, ICG and other TPGs use.

I have an idea for a new slab that will help against tampering and fraud.

Thanks,

G.E.

cool!! i hope your idea is used and makes you some royalties

but remember, as soon as you build a better mousetrap, the mice get smarter

 

Yeah...I do also. It is called RFID inside each slab to uniquely identify each coin. Very difficult to counterfiet radio frequency. The crook would have to know the frequency for each one.

 

cute idea, and welcome to the forum.

 

And the cost of slabbing will go up by an extra "few" dollars. Great - it's only worth for coins that are worth several hundreds but justifiable.

 

Thanks for the welcome. Correct. The cost would be justified for high dollar coins. I would certainly reslab several of mine if PCGS were to offer such a service. Wave a coin over a personal RFID reader and coins are automatically checked against the central database. Protects seller, buyer, and the reputation of the coin grading companies.

 

According to Doug, NGC slabs about 150,000 coins a month. 1.8 million a year.

Are you advocating each coin having it's own frequency ? That's 1.8 million different frequencies a year.

Or are you thinking one frequency, and each chip has its own unique info ? THAT makes sense.

They're even doing that for dogs... they implant a little chip with the owner's info in case the dog gets lost.

 

Each chip would have its own unique identifier. This is already done at the pallet and case level of many consumer products. There is a vision to eventually have item level tagging of most consumer products to do away with the bar code system.

 

RFID tags are gaining widespread use. Walmart i belive is helping to lead the way requireing all their manufacturers to include RFID tages in all their shipments. i am not sure if that has been implemented as of yet, but if not, its on its way.

RFID tags are small, but im not sure if one could be hidden in a slab. Slabs can already be opened, and quite possibly resealed. So if they can be opened, could the RFID tag inside be swapped with a different one?

 

slab ideas

while you're at it...............figure a way to make 'em air tight!

 

I doubt your idea will result in any royalties. Anybody could go around saying 'put RFID tags on the car, and on the boat, and on the soup can, and on the lawnmower, and on the dog...'

 

Neat idea, but I don't really need any more RFID tags in my life. I have a hard enough time keeping multi-national corporations from intruding into my personal space and tracking every purchase I make so that I can be targeted and bombarded with advertisements. I've read quite a bit about this technology, and there's a lot to it, but here's a quick overview: http://www.news.com/2010-1069-980325.html

 

The TPG do not give out this information. It is (somewhat) tightly guarded. Your best bet would be to contact a TPG and see if they have any interest in listening to your idea.

 

Try contacting the China embassy. They are presently counterfeiting coins and lately the slabs so they must have a few organizations that could make them for you. Not exactly sure what your suggestion would accomplish. I've seen slabs opened, coins replaced, slab resealed so that it could not be detected. So the only way your suggestion would be of any use would be if they could implant the slabs with something that would start honking and flashing lights like a cars burlar alarm. Of course if this was done many places in China would become noisy. No organization would publish the source of thier plastic slabs due to the massive run on them from all kinds of people wanting to start thier own TPG services. We have enough already including China.

 

The problem with RFID is security. You can easily modify data written to a device with RFID.

 

Absolutely correct.

 

The last post to this thread before yesterday was in 2007 I believe. Let me add by saying that RFID has so little security as to have none.

 

Those are the ones being countfieted. Makes good sense. If the grading services had a dollar value threshold set for installing the RFIDs it would work. Offer it as an option on lesser valued coins.

 

Personally if I was a thief and saw the number on a slab I would remove the coin from the slab prior to hocking or selling it! Mostly thieves want easy money and not trying to get full price. Now other persons swapping coins and what have you is something completely different.

So eliminate that and you got something.

 

Each slab would have a unique RFID number linked to the slab serial number. The only way a RFID chip could be cloned for a fake slab would be that the counterfeiter would have to have to physical possession of EACH slab he counterfeits. They could not simply steal online images and generate a legit slab number on the label. Cost of each RFID tag? About 4 cents.
