Hello.
I'll try to keep this brief and informative

For some time now I've been inspecting dates on slovenian 1 € cent coins. Only years 2007, 2009 and now 2015 were made for circulation, so I only inspected those.
It seems that 2007 had major troubles with die chips. Every other coin I find has some sort of defect on 2007, being either a filled 0, or filled spaces between digits.
For 2009 it seems they made digits a bit more narrow. It seems that this did partially fix the problem, because defects on 2009 are rarer, but still there.
In 2015 Slovenia issued 1 cent coin again for circulation, this time with wery thin digits in year. So far, after 200+ coins, I have not found a single defect on those.
Coins od 2007 and 2009 were minted in Finland, but I cannot find origin of 2015 ones.
Below are some photos of various defects. (First 2007 is almost normal, and first 2009 is normal.)
Thank you
