DVCollector Bedrock of the Community United States 10045 Posts	Posted 12/03/2010 3:07 pm This is a very dramatic example! Notice how the spreading of the secondary image is irregular, and in the direction of the rim of this coin? Notably lacking is separation between the doubling in areas where I'd expect such as the star points. While I don't collect Euro coins, I think the principle is the same for any die-struck coin. I'm of the opinion that extreme die wear is the cause, but I don't understand why the date shows more wear than other parts of the design. Very interesting coin...I want to hear other opinions too.

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 12/03/2010 3:53 pm I agree with extreme Die Deterioration, it is not a double struck or doubled die coin. The center is nickel brass(75Cu/20Zn/5Ni) while the ring is 75Cu/25Ni, the harder outer ring would wear the dies out quicker than the softer center. If you looked hard enough, I bet you could find a 1 Euro analogue since it has the same metal compositions in an opposite fashion. The Die Deterioration is certainly stronger than usually seen so it is a good educational example but not really worth more than face value. Report this Post to the Staff
Kingz Pillar of the Community Netherlands 626 Posts	Posted 12/03/2010 4:03 pm I guess we are all entitled to our own opinion, but the last comment won't convince untill clearly pointed out and proven. Don't get me wrong I appreciate your explenation and opinion, and it is nothing personal... However I saw so many Euro's which I always check on possible errors, and I never once saw one like this during my experience. I have checked it at numerous different places, and with different collectors like ourselfs, but this is the first time I hear this explenation... you could be right ofcourse, but I don't know how many experience you have with these coins? (Euro's, especially 2 Euro coins) Anyway, I will gladly listen to some other opinions / arguments :) Report this Post to the Staff

biokemist6 Bedrock of the Community United States 12437 Posts	Posted 12/03/2010 4:43 pm Kingz, I am not dealing with opinion here, I am stating an analytical fact. Coinage metal composition has a direct relationship to die wear- the harder the metal, the faster the dies wear out- and CuNi is one of the toughest coinage metals around besides Canada's use of pure nickel planchets. Anything other than die wear would affect other portions of the coin as well, not just the outer ring. Notice how the effect is directed towards the rim of the coin? The cold flow process of striking a coin causes erosion on the outer portions of the devices due to the expansion/flow of the planchet during striking. The die erosion starts out on a microscopic scale but it eventually becomes prominent enough that it imparts a doubled appearance to the devices. You are correct that I have little experience with Euros but I have been collecting for over a quarter century so this is not my first rodeo Report this Post to the Staff
DVCollector Bedrock of the Community United States 10045 Posts	Posted 12/03/2010 7:27 pm I also looked very carefully for signs of repunching or die doubling in the date area. It's what I specialize in--repunched dates and overdates on older European coins: Sweden, Iceland, Denmark, Belgium. As a comparison, I have posted many photos of overdates on this forum.
