Something I noticed on NGC slabs... I never saw before

Yesterday while inspecting 4 different era NGC slabs in direct sunlight (Post Office Parking Lot) with a 10x loupe (NOT a Hubble Telescope) I noticed that the NGC clear acrylic has dimples.

It's completely micro granular, as some of these spots where cast on the coin from the sunlight under rotation.

Anyone else ever seen these under close inspection... or am I coming down with a bad case of Rabbititus

I have notice it. It really affects early proofs in my opinion, but I usually crack out the coins from slabs so it isn't an issue.

Great... always good to know I'm not alone!

Wonder if NGC does this for a reason (?) as paying a bit more attention this type of acrylic, it softens the overall look of the entombed coin IMHO.

I thought you found some small print where it said, "Graded In China".
But there have been other threads on this here and no, I won't search them for you.

I usually just check to make sure that they don't say "RNOWLEDGE,INTEGRIGY and NUNISMATISTS"

that's one reason that I don't particularly like NGC tombs. Those dimples really affect my eye when looking closely at the coin through them.

Even the early no line fatty slabs don't look completely clear to me, always seemed like something was interfering with my view. Could be that I'm 200 years older than moses, but I prefer to blame it on NGC.

I've noticed this. This makes them a pain in the arse to photograph unless you polish the grunt out of the slabs first.

I have noticed the DMPLs before, but it doesn't affect my viewing of the coin.

10x looking at the clear acrylic in the coin cutout area and all along rest covering the white acrylic center... you'll see em EVERYWHERE!

I just want to see what's behind this polymer/plasticized,acrylicized/injection molded stuff with a label sandwiched in between for good measure.

I've seen it, but never moreso than today. I was editing images and found that I had lit a coin just the way needed to make a whole patch of those dimples glow. Now I have to reshoot

Put some slabs in the trunk of your car on a real hot summer day -leave them there until temp. reaches 150 -160 degrees.........

then study the plastic !

I don't care for NGC as a whole and now I can add this to the reason why. I think I have two NGC slabs {(1961) 1C CSA-Bashlow Restrike Copper and a 1967 25C SMS MS68} I may have a moment or two to "look into these dimples" thing. I hope I don't have a eye spasm looking at them.

if you are talking about the area over the coins, i havent noticed it with ngc slabs but have with pcgs various gen, slabs. it is an even faint pattern. maybe once every 10k images.

For some strange oddball reason, out of some 450 slabs I have, only 6 of them are NGC. They're like that kid you stick out in left field and pray he doesn't get any fly balls. Hmmm, there's an analogy in there somewhere.
