That hanger looks great, comes out clear and strong by far the best one I've had the chance of seeing there are a few in my own collection. Thanks for letting me know that the PLs are not immune from these errors!

One of the interesting things is that none of the 1965 matte have the large bead variety (all of them are small beads).
Also, a couple of 65's, still in plastic, have a struck through thread feature on the obverse. That's probably not so unusual given the high number produced.

I don't know, I can't really tell from the pics, but first inclination is not to call these a matte finish. I mean what exactly used a matte finish in 65? I'm almost inclined to think these are damaged in their sets like other coins I have come across. I have some quarters still in plio that looks like they were peed on by rabid squirrels.
Before you guys get on me, specimen sets were made from working dies, not the other way around. So I can't see these being half complete dies either.

I have examples of each, in ultra heavy cameo. I think this is worthy of a look under the SEM, to see if the texture is primary (i.e., imparted on the strike) or secondary (e.g., rabid squirrel pee).

That's something to look into.
Perhaps there is an environmental issue that had a damaging effect upon these coppers. If there was some sort of potential damaging element present at the time the PL's were sealed, then perhaps that might account for the unusual finish developing over time.
It's time to check some of the more recent sets to see if something similar occurred.
I just saw your post SPP, welcome back. It will be interesting to see what an examination will reveal.

@Ugly, True, it's not that easy to see those particle like things on the coins under normal light source ( like sunlight at daytime ) and under naked eye. It's also not that easy to take those pictures. But under the bulb light and tilt the coin some angle and use the 10x loupe, you'll get clear details. Please feel free to check the pics of 1964 1-cent Pl one in my picasa web album, I think should be able easy to tell them.
For terminology of these kinds of coin, not sure yet. I used the "Matte" just to make the description easy. I agree it was not accurate. How about Matte Like Finished Error?
Agree with @Staircase, it seems like has something to do with the environmental issue before sealed in sets. But just guess, had to wait some professional inspection.
Thanks everyone!

Hi there. I was taking another look at this topic and found no distinct verdict with regard to whether or not the dull (matte-like) finish was due to environmental damage or not. The puzzling thing is that this effect is apparent in consecutive years.

That's good to know and puts the issue to rest. Thanks Scissel and 54 for the info.
