What is meant by "Each Strike"?

When entering coins, I see a double green check and the message, "You own a coin of each strike of this coin."
What does that mean?
Thanks

Hi,
Normally you get two green ticks if the following situation occurs:
-That coin stroke only one year, and you own it.
-That coin stroke for multiple years and type (normal/proof) and you own them all.

In this case, KM175 is one-year type coin, so you will get two ticks directly.
For KM170, you need to collect coins year 1941, 1942, 1943, and 1944 in order to have two ticks.

Does the icon with message, "Verified sheet complete year list" add any information?

one tick: you have at least one coin
two ticks: you have at least one coin in every line
verified sheet: the coin is in the catalogue and the informations were verified by a referee or catalogue admin
complete year list: the year list is locked and a normal member can't add new year lines

Thanks Guys. I'm really enjoying the whole idea of a checklist. It might be that I'll enjoy a little organization in my life.
