Hello! I am just a beginner in studying the defects of euro coins, and I have several copies, the value of which I cannot estimate in any way, because... I see coins with similar defects on ebay for quite large sums, but other sources write that such defects do not exceed 100-200 euros.
I have one coin from 2002, Italy with Dante Alighieri. There is one star missing on the obverse of the coin, apparently a minting error.

I have also 3 coins from Germany, 2 coins - 1 euro, and 1 - 2 euro with excess metal and offset from the center of the coin on the obverse of the coin.
Please help me evaluate these specimens.
