I have a preface to Lanting written by Lei Zhenmin, which is lowercase. How much can it cost?

First look at the appearance and preservation.

Secondly, look at the author and font, according to the information given by the landlord ......

If it is well preserved or has been wax sealed, the value ranges from 5000 to 8000 yuan.

If it is slightly damaged or wrinkled, the price will drop slightly, but overall, it will be up to 4000 yuan. ......
