AboveP233-Germany Generalgouvernement 1940 Official Stamp 24 Groschen Michel D21
This looks like a Generalgouvernement (German-occupied Poland) official stamp, 24 Groschen, 1940, commonly listed as an official stamp / Dienstmarke. A reference page identifies the 24 Groschen official stamp as Michel D21, first issued 5 August 1940. Retail examples appear at about €2 from a dealer, and comparable eBay listings for single examples are in the low single-digit range, around £1.50–£5.50 depending on condition and whether used, mint, or expertised.
For your example, the stamp appears mint hinged / regummed uncertain / gum disturbance on reverse, with visible toning and hinge remnants on the back, plus slightly uneven centering. That puts it in a lower collector grade, so a realistic market value is about £1–£3, with an eBay Buy It Now target around £2.49–£3.49, or auction start at £0.99. That estimate is an inference from the comparable listings and the visible condition in your photos.
