It's me again, I'm sorry if I'm bothering with these posts (I feel like a spammer).
Here I let you this pics to read your opinions. It's a 10eurocents coin without the "LL" of the designer. I leave both pictures, the one with "LL" and mine. I guess it's a filled die but I also think that we only can see clearly this kind of error if the coin is uncirculated. It could be a spoiled coin too!!
With "LL"

Without "LL"
