the inscription is the name and number inscribed by the calligrapher, and the inscription on the seal is "the treasure of Qianlong's royal tour", which is the special seal of Emperor Qianlong of the Qing Dynasty. Qianlong period is one of the peak periods of cultural and artistic collections in China history. Many precious cultural relics and artworks have been preserved to this day, so the value of this pair of words may be high.
However, the specific value still needs to consider many factors, such as the integrity of the work, the state of preservation, the quality and content of calligraphy and so on. In addition, the market price will change with time and demand. Therefore, if you want to know the specific value of this word, I suggest you contact a professional art evaluation agency or auction house for appraisal and valuation.
