There are six pieces of Yu Youren's calligraphy "Song Zhengqi". Is it collectible and what is its value?

Song Zhengqi was written by Yu Youren in the 27th year of the Republic of China (1938) at the age of 60. This is his work after he put forward four principles of cursive script: easy to recognize, easy to write, accurate and beautiful, and advocated standardizing cursive script. Song Zhengqi's cursive script is a model. Song Zhengqi is a poem by Wen Tianxiang, a patriotic poet in the Southern Song Dynasty. Song Zhengqi's carved stone is now in Room 7 of Xi 'an Forest of Steles.

Landlord, don't listen to those who say how much it is worth, you, because this is a modern inscription. Although it was written by a famous artist, its value is not high. The circulation price of six articles in the market is about 50~ 100. However, if there are autographs of other celebrities on it, the price will be different. Because it is a modern inscription, there is no need to worry about damaging the original monument, so the rubbings are of great output and naturally cheap. If you travel to the forest of steles in Xi 'an, you can buy it at any time. Unlike some ancient ruins and isolated ruins, it is no longer possible to develop them or their number is limited every year.

So the expectations of the landlord should not be too high. Although my words are not pleasant to hear or disappoint the landlord, the facts are really as I said.
