Post your world error coins

Picked up another India coin or two, I just wait for them to arrive to post. Here’s one that arrived. 2016 10 Rupee off center.



After realizing just how many error India coins there are out there, I likely will not purchase many more. Perhaps I’ll try to get one of each error type from that country.

I just picked up this amazing 1871 200 REIS Brazilian coin

 

Wow, that’s a significant amount of delamination!

 

Yeah, but, to me, is hard to understand how occurs a delamination like that, because it's huge. The question is: How nobody seen it when occurred?

 

It’s literally just the metals not mixing properly. They can be big or small. And sometimes they break off after leaving the mint, while they are circulating.

I can understand, but in this case, at least to me looking longly to the coin obverse, seems the coin was struck after delamination. The letters REIS appears on the delaminated part.

 

I can understand your confusion. Think about the amount of pressure the dies strike a planchet with to produce the image. Metal literally flows from a flat planchet and raises up as other parts are smashed down. If that happened before the planchet was struck, the metal would’ve moved in and filled that gap. I’m not an expert, but I’d say imagine a (laminated) planchet like a stack of papers. Take a pen and press it into the pages. Remove the top couple of pages and you’ll still see an indent several pages down. That’s why you still see the design even though the lamination peeled off. Here’s one of mine for comparison.

 

Great explanation!! Now I really understood what delamination means . Thank you very much @Seattlite86.

 

Fantastic. And great find. Thanks for sharing.

 

Is this considered an error?

 

Can you clarify what you think you see?

 

the lines on the flip are the tops of both sides. it is rotated 90 degrees

 

The best way to show rotations are to take a photo in front of a mirror, showing both sides at the same time. See if you can get one like that.

 

best I can do

 

These Euros are medal alignment not coin alignment.
yours is normal for the issue.

 

medal alignment is both side in the same direction, yes?

 

Medal alignment is when you flip the coin like turning a page in a book.
Coin alignment is when you flip it from the top/ to bottom.

 

well this coin is definitely NOT metal alignment, then

 

Dan the harp on the reverse stands up, it doesn't lay sideways.
