if you scroll down youll see approximate prices for the coin. i dont know about the accuracy of them, but theyre there
Numista prices are not really based on much at all never really trust them as a collector sorry just we do not have enough people to update them enough at all. Best with stuff like this that is more scarce is to look up the most recent auction that one sold in on acsearch that is in roughly the same shape and then look that auction up on numisbids to get the price it went for (for most auctions this will work) then gauge from there
For common coins from this part of the world, I use the WCN archive to do research on recent selling prices. In this recent sale, a lot of two graded at III /III+ (VF/VF+) sold for 90 PLN ($23). https://wcn.pl/archive/387809
