Price for a Base Set 1st Edition art set (not English)

Hi everyone, I have the chance to buy a Base Set 1st Edition art set (language: Dutch). The seller says they are unweighted so I assume they are light packs. What do you think is a reasonable price for this art set? The asking price is $ 1800. I would like to hear from you.

Looks like one pack sold for $450 previously.

Perhaps you can use that to talk the price down.

Thanks for the link. I appreciate it. I can’t find any other 1st Edition Packs. What does that mean? They are scarce?
