Hey, what exactly are the plastic slabs -- or at least the part directly above the coin -- made of ? I had to get something framed the other day and I came across this Museum Glass that was super-transparent. Seems to me that if the TPGs offereed new slabs with stronger/clearer/reflection-free holders that you might incentivize lots of people to send in for the new slabs with older stuff.....get the picture database updated...and insert new anti-counterfeit stuff included in the slab. Thoughts ?
I have some old rock & roll memorabilia framed behind that museum glass. It is supposed to protect the displayed item from UV rays. I like it.
As mentioned in the photo, it is GLASS and still breakable, as glass is. I've had many a painting and photograph framed with museum glass to cut down the glare, but as I said, it will break as easily as regular glass, so I don't see it being used to slab coins.
Maybe some of the new acrylics or other composite plastics are an improvement from what was used 25-30 years ago ?
I'd be willing to pay a few $$$ more if it was better plastic/composite/glass/whatever....improved anti-counterfeiting...and increased the picture database. Preventing fraud is a HUGE boon to the hobby.
Every few years, the TPGs update their slabs to make them clearer, more scratch resistant, stronger, etc. They also have experimented with different coatings. Glass would be bad because, as mentioned, it is too fragile. Imagine how easily your phone shatters - would you want a coin in that? And, the exact type of plastic they use is a trade secret. They won't tell you.
A sale place for museum glass and some info. http://www.c4gallery.com/merch/tru-vue-museum-glass.html Jim
Makes sense it would be. But seems to me I've read about the type of plastic it is and the company/ies that makes the slabs for them. But I can't recall off the top of my head who it is/was.
Thanks for the correction. I had always differentiated acrylic from plastic in. My mind as two entirely separate materials.
There's many different companies who make and sell slabs, not just the TPGs. Some are made of the same materials as the ones the TPGs use and some aren't.
I’ve used it for watercolors and needlework to prevent fading. I usually just use regular glass and avoid sunlight but on a few hi dollar or extremely delicate items I have like the pair of samplers dated 1789 and 1794 that had literally never seen daylight and the colors in the thread were as bright as the day they were made Many better frame shops carry it too
