None in shops or trades, unable to search forums because the feature is currently down.... and im "newbie" here :v
item :Common Lifelike Hipottu Doll
rarity: 160 ( game prize ) Official price: 0 ( wtf ) overall price: not enough purchases. ( wtf again... )
usually the lifelike dolls hover at around 25k sp within a few months of them being released. There are a lot of collectors though, so you could throw it into a shop for a few million sp (I wouldn't go more than 10 and tbh if it were me I might do 3-7 to see if I could get lucky, like I said they're basically worthless after a couple of months so quickselling is your best bet) to see what could happen! I hope that helps a bit ^_^
Also:
official price is how much that item would cost if you bought it from subeta stores, rather than user stores. So for example, a holiday item from the libertine lounge may cost 15 lounge trinkets, so the official price would be 15. or if an item is sold in the official subeta shops for 4,250 sp, its official price would be 4250. the hipottu's price is 0 because they aren't sold in official shops, so there's no official price.
the overall price is for user shops. yours says not enough purchases bc there aren't any in user shops right now. so like, that item that I said 'oh the official price may be 4250,' there could be some in user stores for 3.2m sp, so the overall price would be 3,200,000. Sometimes the overall price is higher than the official price because the item is rare, or new, or desirable.
I hope that helps a bit ^_^
