I have finally decided to research the topic of Slovak proof coins, because the mintages given by Numista seemed unreasonable.
For example:
Lets look at year 2002. Here proof has a mintage of 16 100, which was completely unreasonable, since I have never seen one. The coins found in sets are clearly not made in proof quality.
While here: N#2486 , no proof coins are listed at all, and the yearline has just “In sets only comment”.
I have been able to find the old version of Kremnica mint website on wayback machine which has all these sets. (Currently they do not show any information unfortunately.)
For 2002 they list 2 sets with standard (I suppose just UNC coins): https://web.archive.org/web/20080916184406/http://www.mint.sk/arch_nbs_2002.php

Total mintage is the same as the mintage for “proof” coins given by Numista, so it seems Numista is wrong here.
Why do I think they are not proof? Looking at other years that definitely has proof sets (2000 and 2004) we see that they marked proof sets as proof:

This would mean that in 2002 no proof sets were issued.
However, before requesting the deletion of yearlines, I want to ask if anyone knows whether the non-proof sets had just standard (UNC) or BU quality coins in them?
Also, if I am wrong anywhere (for example there are other sources that are as credible as the mint itself that claim these coins are proof), please correct me.
