Szeląg koronny (1663) + Szeląg litewski (1664) - Jan II Kazimierz

Hello!
Please help me identify the exect types (if it's possible) of these two coins from Polish–Lithuanian Commonwealth.
The first one is Szeląg koronny - Jan II Kazimierz Waza Ujazdów 1663.

On obverse: portrait to right, letters T.L.B. under it, legend around the portrait - IOAN CAS·REX
On reverse: coat of arms in the shape of an eagle, legend around - SOLID·REG· (Korwin arms (Wikipedia says that a raven with spread wings, holding a ring, and standing on a crown is one of the variants of Korwin arms)) POLO·1663·  (without dots between numbers)

So this is most likely one of the types with T.L.B. and Korwin arms, but I have no idea which head type it has.
If it helps here are some very similar examples from the internet:


The second one is Szeląg litewski - Jan II Kazimierz Waza Wilno 1664.

On obverse: portrait to right, letters T.L.B. (not sure, almost not visible) under it, legend around the portrait - IOAN CAS·REX
On reverse: a picture of a knight on a horse, HKPL monogram under the horse, legend around - SOLI MAG(C?) DVC(?) LIT(?) 1664 (crown)
So it is probably one of the types with T.L.B. and HKPL monogram, but the same as in the previous case I have no idea which head type it has.

Thanks a lot in advance!

Lithuanian schilling of 1664 type is classified based on lettering and punctuation. You have most of punctuation and lower lettering destroyed by time.

The only type that fits is 2324 in https://en.numista.com/literature/volume.php?id=2509 book. Rest got dots between SOLI MAG DVC LIT and year. Even that type has dot between LIT and year.

1664 year is lucky as it can be only Vilnius mint or fake. Other years got multiple mints. If your classification is based on looks of king, you are classifying originals and counterfeits in same category.

tokul, thanks a lot for the answer!
I decided to look at this book, and it seems like a few more variants are possible — for example, 2326 or 2327 — because there is no dot after "IOAN" (?) on the obverse of my coin, and we can also (maybe) see a dot after "MAG" on the reverse.
Anyway, you were right: many details have been lost over time or during the minting process, and now it's hard or almost impossible to identify the exact type of this coin.

I just wanted to identify this coin correctly to add the proper type to my collection on Numista, but it seems that in this case, it's better to add the coin as a general entry, without assigning a particular type.
Also, you mentioned classification based on the appearance of the king — so, if I understood correctly, we should classify these coins by the portrait’s appearance only when we know it's a counterfeit, right?
