I've gotten it 10 times and it always gave 17k.
cadomax is not perfect. For example, I didn't find

there; some rarity coeffs seem to be wrong (but in that point we have to believe what cadomax says), the N64 pad gives 100k, not 17k (according to the videos),

gives 1600, not 1200 (which cadomax says), ... So I think it is another mistake.
But thanks for the pearl

I will add it ("Green-Moss Pearl" - correct?)
