Hello everyone,

I have a 2 Euro Germany 2003 "G" coin that may have a mint error.

Specifications:
- Country: Germany
- Year: 2003
- Mintmark: G (Karlsruhe)
- Denomination: 2 Euro
- Diameter: 25.75 mm
- Weight: 8.5 g
- Material: Bi-metal (inner core: nickel brass, outer ring: copper-nickel)

Error description:

- Right side: raised rim with ribs on the yellow core

Photos attached:
- Obverse (face)
- Reverse (2 Euro side)
- Edge / rim
- Close-up of suspected error

Could someone help confirm if this is a mint error and provide an estimated value?

Thank you!

Welcome to numista,

at least you have a well-worn coin, but I cannot see any double rim?

The fusion points of the inner core and outer ring often look like that, unless it is a catastrophic overspill due to a badly set core it's nothing special and happens all the time.

Thank you for your replies.

This coin does not only show normal fusion marks.
On the left side there is a continuous inner rim (crescent), and on the right side the core shows clear ridged metal, like displaced metal from the bonding process — it is not typical wear.

Please see the attached macro photos.
Any expert opinion is appreciated.

Hi there,

I think you have pre-conceived ideas, so all the experts not agreeing with you, are charlatans?

Sorry for my outburst, but you obviously already know better than anybody else?

Take care

Hi,
No worries, I am not claiming to know better.
I am still learning and I really appreciate expert help here.

I only wanted to understand whether the inner core edge and ribbed structure on the right side could indicate a striking anomaly or just normal bonding variation.

I am not arguing — I am trying to learn and compare.

Thank you for your patience.
 

Gern geschehen!

Like I said what you have (middle) is not how the perfect coin should look like (top) but a very normal occurrence and unless it is very extreme (bottom) nothing special.

Thank you for your comments and opinion!
I’ve attached a photo with arrows to highlight the feature: on the yellow circle, there is a ribbed ‘crescent’ on the right, but not on the left.
If you have the time, I would be very grateful if you could take another look at this detail.
I truly appreciate your time and expertise, and I have great respect for every professional on the forum!”

Everything probably was slightly shifted to the right. Less material on the left more on the right leading to brass migrating into the striated area of the outer ring and moving away on the other side.
 

Here is an extreme version with the overlap on one side leading to missing material on the other:

Thank you very much for the explanation! 🙏
That makes sense. Mine seems to have a noticeable shift but not as extreme as the example you showed.
I appreciate your time and the detailed clarification!
