I have a calligraphy rubbings of Qianlong Imperial Pen (original rubbings), I wonder what its value is?

According to experts in the collection field, the rubbings of Ganlong Imperial Books are not very valuable. The stone carving of Meihuating Pavilion in Shilipu Village, Shahe City, Hebei Province, which is a famous figure Song Jing in the Tang Dynasty (including the only plum blossom poem in Qianlong calligraphy, Dongchuan poem and ancient plum blossom painting in China), is a national key cultural relic protection unit. Its stone rubbings are of great collection value, especially the "Ancient Plum Blossom Map" painted by Gan Long Yu Bi is extremely rare in China. A set of stone rubbings of Plum Blossom Fu written by Qianlong Imperial Pen cost more than 2,000 yuan, and the market price will not be less than 5,000 yuan. And it's not available on the market, so it's hard to buy.
