If anyone wants to know what a type of plastic is, whether flip or holder, send it to me. I'll identify it with Fourier Transform Infrared Spectroscopy and a library of 250,000 common materials to match to. The identification takes all of 20 seconds. I'd answer some of these questions, but I don't have any opened holders as I am not a crack out artist.

One thing I really don't like about the difference of PCGS and NGC plastic is NGC uses a shell casing that is highly shiny compared to PCGS. It highlights fingerprints and smudges terribly. I put a few morgans in the retro NGC black holders last year and I hate how shiny the plastic is with the black background. I'm a solid PCGS guy but even with my issues with NGC plastic I'll still use them for lower value errors sometimes as PCGS wants an arm and a leg and on a seperate submission with seperate shipping for errors.

Do NOT confuse inert with air / water tight holders.
A holder stored under poor conditions (say a damp kitchen with lots of cooking) will allow some environmental components to enter. Even the newest PCGS holders, while water tight are not air tight...
It's also important to realize that all components - the shell, insert, label and ink(s) used - need to be inert or the contents may toning over time. Some holders from some companies are notorious for this...
For example older PCI holders have both toned coins and the paper label often exhibits foxing.
There was a generation of PCGS holders where the label color wasn't color-fast and they are known in blue, green, even yellow.
etc.

PCGS has a plastic scratch proof case. I do not recall reading anything on PCGS' submission form alluding to an upgraded service such as this. Plus, one of my most recent PCGS-slabbed world coins came back to me with fine scratches on both sides:  PCGS requested close-up shots of both sides displaying the alleged anomaly. I just had to resubmit my slabbed coin to them using a pre-paid shipping label that they emailed me. I attached a photo in this thread of how minor the scratches were just to emphasize that PCGS was more than willing to make things right no matter what the new scratches looked like. My holder also had another odd phenomenon going on; check out the internally-located small piece of crescent-shaped discolored plastic; see the attached photo:  If a finger rubbed across both the obverse or reverse sides no undulations or roughness in the hard exterior slab cover could be felt above this internal half moon object. The scratches, on the other hand, could be detected by running a fingernail across the external surface... Their rep. indicated that either issue would have justified a 100% PCGS-covered redo. I never received a 100% explanation on what actually happened and really didn't care since I'm sure my slab made them review their outgoing QC processes a bit more closely; plus my re-slabbed gold piece arrived immaculate the second time. I speculate that most likely they were having some unique problems with their equipment at the World Coins site in order to have a double whammy like this one. In summary, PCGS took care of everything politely and professionally including round-trip insurance, freight and any related processing fees. I'm sure it did help expedite things, however, being that I notified them within 48 hours of receipt since it arrived to me on a Sat. On a side note, the mark of any great company is their ability to quickly resolve unanticipated problems with minimal collateral damage to their reputation or to their customer's positive perception of the company. |

I learned one thing the hard way today. PCGS and NGC holders are not made from the same kind of plastic. I recently received a batch of coins from a Heritage Auction. As usual they plastered them with all kinds of stickers. Even covering the the center part of the reverse on a few of them. They also like to use stickers that leave behind a lot of cruddy residue. I brought home a can of 3M Natural Adhesive remover to try to get the residue off. They said it is safe on most plastics but to try it on an unimportant area first to be sure. I tried it on part of an NGC holder first and it worked very well taking all the residue off and not harming the plastic at all. At this point I should have tested it on a corner of a PCGS slab but made the incorrect assumption that it would work in the same way as the NGC holder. Well several minutes later I learned that it attacks the plastic of the PCGS holder very badly. So now I have a coin that has the reverse of the holder looking like it's been through a war. It's completely blurry and lumpy. The coin's worth about $250 so I guess I'm going to bite the bullet and have it re-holdered.
So in case anyone was interested. Whatever kind of plastic PCGS and NGC use, they don't use the same kind.

Are you certain that you are talking about PCGS here? In the last 4 years and over 1000 submissions later I have never found this to be the case. |

Best guess then would be that PCGS uses polycarbonate (and a scratch resistant polycarbonate upgrade).
Polycarb or PC doesn't have great resistance to citric acid.
I always assumed it was PC with their scratch resistant PC and that NGC used PC as well but didn't have the scratch resistant material.
If the NGC's are more resistant to the same citric acid, this wouldn't seem to the be the case anymore.
On a side note, no excuse for Heritage to be using stickers leaving a sticky residue like that.
No reason you can't solve this problem within 30 days Heritage.
No reason other than lack of desire that is I guess.

For removing sticker adhesive from coin holders, I keep an eye dropper filled with vegetable oil. I place a drop over the sticker, smear it around and wait about an hour. That usually allows me to easily peel it off. Remaining residue can be wiped up with a cotton ball. If the sticker has a plastic coating, I will scratch the surface of the label and allow the oil to penetrate. As for sending Heritage the bill, I have not found them willing to resolve issues in the past.

I actually was in a very similar situation, but a little different. I bought a coin through Heritage's Make-an-offer program and when it came, the original Heritage sticker was still on it, from their 2011 February Long Beach auction  . When I tried to take off the sticker, not only did it leave residue, it also took off many flakes of the PCGS hologram . To get off the residue, I foolishly tried acetone first  . Made the plastic all wavy and stuff. I tried contacting Heritage to help me get it reholdered, and their representative seemed helpful at first. They first suggested Goo Gone for the residue. When I sent them after pictures though, they said they can send it for reholdering for me, except that I would be billed the costs. Because it was a make-an-offer item, it is considered to be sold "as is," so they wouldn't cover the reholdering costs. I eventually sent it in myself through a dealer. Because yours, Tbone, was directly from Heritage and it was their stickers, maybe they'll pay up for the reholdering or send them in for you (probably with their large dealer discount?). Regarding removing adhesive, I've found (a little too late) that Goo Gone does the trick without damaging the holder. It might leave a little smell and greasy feeling but that can be easily removed with some soapy water. Good luck to you, Tbone, in trying to get Heritage to pay up! Edited by coinlover168
