Contemporary calligraphers have no auction records. It is difficult to estimate the price. It is recommended not to trust the organization that gave you the evaluation certificate. The state does not recognize the market, nor does it recognize the market. If you want to know the value, go to the auction company that doesn't charge in the formal early stage and try it. Don't believe the valuation given to you by the charging company before shooting. The main purpose is to make you pay. I know if I can film it.
Companies that don't charge before shooting: Guardian, Poly, Christie's, Hengtong, Sotheby's, Shi Kuang, Baolong, Hanhai and so on can all try. If you can't deliver it yourself, you can call me.
