This is the same king, Zygmunt II August, the king of Poland and the Grand Duke of Lithuania in the years 1548-1572. Crowned king during his father's lifetime in 1530.
You have the answer in the legend, Lithuanian half a penny *MONETA* MAGNI () DVCAT* LITV,
The Kingdom of Poland and the Grand Duchy of Lithuania at that time were in the union. Polish coins were in circulation in Lithuania, while Lithuanian coins were in Poland. On Numista, in my opinion, there is a mistake when adding this penny to the Polish Kingdom
I don't have any knowledge about the coin(s), however I see a clear difference in the pictures on Numista:
The lithuanian has LITVA in de reverse legend, whereas the polish one has only LITV. Furthermore, the depiction of the horse seems different, and your coin resembles more the lithuanian one in my opinion. Are we sure that both are the same coin?
The Kingdom of Poland and the Grand Duchy of Lithuania were ruled in a "personal union" with the same monarch presiding over both places from 1386-1569.
Coins struck in the Lithuania mints during this period often show up under both Poland and Lithuania, as we see in Numista.
The ½ groat coins were struck in large quantity, with many small variations in spelling and punctuation.

No Lithuanian will agree with you. Yes, there was a personal union then - one king for two countries. Polish crown coins, were minted on the Polish foot - the weight of the half-penny of the crown was determined at 1.03 g. Lithuanian coins minted in Lithuania, here specifically in Vilnius, the capital of Lithuania, were minted at the Lithuanian foot. The weight of half a penny according to the Lithuanian rate was determined at 1.28 g. The coins were minted using the al marco method, so there are large differences in the weight of each piece. However, these countries had different minting rules. The monetary union between Poland and Lithuania was introduced in 1580.
A zatem, jeśli moja moneta nie jest całkowicie zużyta i z wyglądu nie uszkodzona i waży 0,85 grama, to czy najprawdopodobniej została wybita w Polsce?
No, it was minted in Vilnius, Lithuania. Al marco method (Italian: marco "mark, sign") - a method of issuing coins according to a specific weight unit of bullion (eg pound, fine), from which a strictly defined number of coins were minted, but differences in the weight of individual coins were allowed. The coin plates were hammered, mostly by hand. the sheet metal had a different thickness in different places, so some discs were heavier and the other lighter. Then coins were minted on these discs. Finally, all the coins minted once were to have a specific weight together.
