Collector 2 zlote are legal tender but definitely not circulation pieces, NCLT, no matter high mintages. These 5 PLN will obviously be cirtculation pieces, which is much more interesting in my opinion and then you have no excuse not to collect them
Luckily, there are so many helpful collectors all over the Poland from whom I'm sure you can make some good swap, on face value or whatever. 5 PLN is still considerably less than 2 euros and in my opinion euro coins are biggest pest, especially now when two comms per year are allowed, it's damn expensive and almost impossible to cope with every year.
