User blog comment:AliCake/Worths of these masterpieces and another item/@comment-35646663-20180807073833

Chocolate froggy is a popular artist and there are many copies throughout the game so I'd say her masterpieces are worth only about a short collar. They are hard to trade away, like Hyenine1's masterpieces.

The headdress and spike masterpiece.. obviously just traced, I honestly don't see the point of these pieces and why I see them around so much but I'd assume just a spiked wristband only. The more likes >> The more rarity it is.

If you can get a masterpiece to 1000 likes it can easily be a good short or long collars worth. Especially if it's realistic, then a good long.

Flower brooch is an unreleased nonmember promo item, so yes it's worth a ton. I'd recommend waiting until they're officially released.
