In terms of the value of cultural relics, things in the Republic of China were not very expensive. From the point of view of publications, such books are really precious.
Only in the hands of real collectors can a collection show the beauty of its value. If you really want to sell it, I think you should first consider finding a good home for this set of books and let it find a real collector.
Of course, from the collector's point of view, if it reaches his psychological price, he will not hesitate to accept the collection.
From my brief description of the book, my ideal price should be around 3000 yuan, or it would be very good to reach 3000 yuan.
Of course, from some angles, some things can't be measured by the amount of money.
