Last 2019 Purchase: Cool-Looking 2000 Canadian 25 cents Error

Happy Holidays! Want to share a recently purchased error coin. Probably my last one for the year 2019, since I need to allocate funds buying electronic stuff for my family (GoPro, Ninetendo Switch, etc)

It is a struck through error on a 2000 Canadian 25 Cents coin. Struck through in general is a quite common error. However, the area where struck through occurs is quite interesting. Covered the face, but not the crown. Somehow gives me a "wow" feeling, so I have to pull the trigger...

As for the type of struck through. I think it is heavy grease, but not conclusive. What do you think?
