Is the pillowcase hand-embroidered by my old man valuable?

Yesterday, I just went to Dalian Modern Museum. The theme recently displayed in the museum is embroidery in the Qing Dynasty, and the exhibits include pillowcases in the Republic of China and the Qing Dynasty. It's so beautiful that many tourists have been taking pictures with their mobile phones. It is the most attractive embroidery in the museum, and I also took photos. From a distance, it is a word, and from a close look, it is a painting. There are also curtains of the Qing Dynasty, embroidered clothes, three-inch golden lotus shoes and so on. It's all in the museum, don't you think? Besides, the value of things like antiques and collectibles is hard to estimate. When you say it's valuable, it's valuable. If you think it is rubbish, you will buy rubbish if you throw it away. So there are many stories and jokes about collecting treasures, which are even valuable in one person's eyes and worthless in another's eyes. However, emotional factors, as described below, are immeasurable.
