The value depends on the specific situation. Regular natural shape, good texture, oil, and of course high price. But some people have to cut off the bad ones because of the defects in shape and meat, that is, plastic surgery, so it will definitely be more expensive than nothing, so it depends on things. On the other hand, if there is no need to repair, the merchants will not reinvent the wheel because the materials are not good. Note that many shape modifications are not necessarily seed materials, but mountain materials are fake.
