Is Ye Shengxing's seal valuable?

Worth some money. Ye is a famous scholar, educator, archaeologist, seal engraver and calligrapher in China. He used to be a consultant of China Seal Engraving Association, China Seal Calligraphy Association, vice president of China Wenqi Research Association and director of Guangxi Calligraphers Association. As Professor Pan Zhulan said, Ye, after that, is the luck of the country and the nation, which makes history no longer dusty.
