Excuse me, are the following stamps and other stamps printed with "Imperial Japan" valuable? There are links below.

The picture above shows the early common Japanese stamps: 19 14, the old Tazawa paper San Qian stamp. The serial number of this set of stamps is Pu 142, and there are 6 stamps in full set/KLOC-0. Yours is an incomplete set of letters with a face value of three yuan, each of which is worth about 8 yuan RMB.

Other stamps include "Broadcast Gymnastics" and "Mei Lanfang" in the old Git stamps, a Vietnamese "100 Lenin's Birthday" stamp and new york version of Sun Yat-sen's improved stamp. Among them, Mei Lanfang has two stamps, each worth about RMB 150 yuan; A full set of 36 original tickets of gymnastics stamps is worth about 9,000 yuan, and the reprint ticket is worth about 500 yuan (you can't tell whether yours is the original ticket or the reprint, the reprint is thicker and whiter than the original paper, and the original paper is thinner and darker); The rest is worthless, about a few dollars each.
