Lamination flaws

Steveqld · August 16, 2014, 05:29:22 PM

I couldn't see a thread devoted to lamination flaws although I did only get through about 3 of the 22 pages of topics in this category.

One I found recently with something interesting going the width of the coin.

What I originally thought was a delamination but may be a cold shut the 12.00 o'clock on the obverse. It also shows a peel starting at the top of the hairline:

Secondly the obverse showing a raised "mound" running the width of the coin from 12.00 o'clock to 6.00 o'clock. I suspect either delamination or some sort of chemical reaction forcing it up:

And the least interesting a lamination at 6.00 o'clock on the obverse.

Is that a whole raised section from 11 o'clock down through the head towards 5 o'clock?

What a beaut!

yeah it looks like it might split in half, doing well Steve!

Yes. Not sure what caused it though. You can also see some flaking on that raise at the tiara.

What does the reverse look like Steve?

Nothing out of the norm.

Not sure what is happening with these images. I save them at 6" x 6" but it seems to be posting them as 10" x 10"

10x10 is super good for me Steve!

Gee that is such an unusual coin. I've never seen anything like the ridge. There's doesn't seem to be a hair out of place!!!

Quote from: 'Steveqld' pid='57212' dateline='1408175962'may be a cold shut

Yes, its a cold shut. Or several, by the look of it. I would guess that section in the hair might well drop out at some stage.

Nice coin.

I'm suspecting that there is a lamination flaw under the length of the ridge. When struck by the die the metal flow has gone inwards as well as outwards and with nowhere else to go has raised and caused the ridge.

My theory anyway.

I'd expect that this coin is fraught with lamination flaws
and could end up a bit like this penny in a few more decades

What? Oh, you said "lamination", not "lamington"!

ausjack · August 18, 2014, 08:57:09 AM

No Jeff but I found something to help us, a machine

My wife has one of those things - never thought of using on coins! :biggrin:
