1991 LMC Is This A Die Clash?

The pics are bad, the only way I can get close shots is to zoom a bit, zoom makes them blurry. Camera will not focus if I try to move it closer.
Before I posted I did poke at it a bit with a toothpick seems solid, not a gas bubble. Looks way different through the loupe than it does in the pics.

Through the loupe it appears to be a bold line under the E in cents, the line looks to be about the size of the top of the T in trust and in the right general area for that. However the photos make it look more like a blob of metal, so maybe just a small die chip.




Yes, using the macro setting, and a grey background as per your suggestions in my post in the Photography forum. The pics are getting better with practice, I just can't seem to get the close ones right.

I'm saying, no clash. Just a die chip. Keep looking and you'll find one eventually!

Thanks for that explanation stone man, very helpful.
They say you can't teach an old dog new tricks, but "they" didn't know THIS old dog would join the CCF!! I'm learning new things ever day.

Hard for me to see with the photos

The split plating happens most of the time on the outside edges of the devices. Note the locations on these images:



But most often it just affect the outside devices near the rims or the SE corner of the "D" mint mark Zincolns.
When it happens on the Mint mark, it seems to follow a pattern:

When the air reaches the zinc it start to deteriorate. Like examples above. Sometimes you can find it on the inside part of the mint mark and the plating will curl back making it look like a RPM:

The first clue. Look for thw white/gray color in that area affected. It will be on the outside (usually) part of the devices toward the rim. Hope this helps.
