Original winter rims 20-inch SQ5 value?

Hello all, I still have winter bikes left of my SQ5. They are the original wheels with Dunlop tires at the time. While the tires are probably hardly a value anymore (approx. 5 mm). I would like to sell the things anyway, because you take away my place. Now I have several statements about the price. These go from “maximum 200 EUR” to “there would have to be about 1000 EUR”. Can someone give me a more reliable price. If I take the NP from 3 years ago (2669 EUR ) and the cost of new tyres (approx. 1000 EUR) as well as the wear (3 winters with approx. 12000 km) remain about 800 EUR. I would estimate them for about 500-600 EUR. Is that too much? Thank you for your assessment.
