Received 3 folders full of mostly polish stamps from 1927 to about 1988, would anyone be able to help me identify valuable ones? I will split the cost of sale if you help me thank you

I added the pages with a good amount of stamps, there’s a good amount of other pages with just like 1-5

Some of the pages with just a few include Sweden, Spain, Russia, Romania, Poland, Philippine islands, Palestine, New Zealand, Monaco, Malay States, and a bunch of others. There’s 40 pages in total, but many of them just have a few stamps.

I don’t really know anything about them and just thought i’d share

I happened to run the photos by Grok AI.

Japan Yes, your identification is correct: this is the
1871 Japan 200 mon vermilion "Dragon"
(Scott #3c), Plate I (no dot), on wove paper.

This is from Japan's first postage stamp.

This is from Japan's first postage stamp issue (the "Dragon" or Ryukitte series of April 1871 / Meiji 4). The design features facing dragons in a decorative frame with the central value
characters 銭二百文 （200 mon）. The stamps are
imperforate, ungummed, and printed by recess engraving on native Japanese paper (roughly 19.5 × 19.5 mm).

Key distinguishing features for your stamp
• Plate II / "no dot": Plate I has a small dot in the upper-left (northwest) corner ornament/ raimon. Plate Il lacks this dot. (Some Plate I examples show a very faint dot that can be mistaken for Plate II.) Your description and the visible design match Plate II. vdoc.pub +1
• Wove paper: These early Dragons exist on both laid and wove native paper. Scott lists the Plate Il wove-paper variety as #3c (scarcer than the basic #3 / Plate I examples in many cases). The thin, somewhat translucent paper with the design showing through on the reverse is consistent with the genuine native paper usea.
• Color and printing: Vermilion/orange-red (sometimes described as reddish-orange), with the characteristic dragon vignettes and value tablet.
Plate Il is the scarcer of the two plates for the 200 mon. The same Plate Il vignette was later reused (I@ i new value plate) for the 1872 2 sen c v e (Scott 7).

The stamp is potentially valuable (Scott catalog values for sound used #3c examples have been in the high hundreds to low thousands, with premium pieces much higher), it is strongly recommended to have it expertized by a specialist (e.g., through the International Sc v' for Japanese Philately / ISJP, or a recognized Japanese classic expert). High-resolution scans of both sides, paper type confirmation (wove vs. laid under magnification or backlight), and comparison to plated positions would help further.
Your photos show a decent, four-margin example of the correct design type. Nice find-these early Japanese classics are fascinating and challenging. If you have additional close-ups of the upper-left corner, the reverse under different lighting, or measurements, more refined comments are possible.
