AI Appraisal Estimate

This is a philatelic souvenir sheet commemorating the 1991 Bobsleigh World Championships (Weltmeisterschaften im Bobsport 1991) held in Altenberg, Germany. The item features a central postage stamp which depicts a high-speed bobsleigh on a track, with a face value of 100 (likely Pfennig). The surrounding selvage illustrates a stylized map or track layout winding through a wooded, mountainous landscape in shades of green, blue, and brown. The text at the top is printed in a clean sans-serif typeface. This specific specimen has been postmarked, as evidenced by the black circular cancellation lines extending across the lower portion of the sheet, indicating a 'used' postal status. The paper exhibits some signs of historical handling, including slight fraying or unevenness along the top edge and light surface wear. The craftsmanship reflects the late 20th-century German philatelic style, utilizing multi-color offset printing. The overall condition is fair to good, though the heavy cancellation markings and slight edge wear are considerations for collectors of used postal materials.

I have virtually examined this 1991 FIBT World Bobsleigh Championships (Altenberg) souvenir sheet. The item appears to be an authentic issue of the Deutsche Bundespost from the post-reunification period. The central 100 Pfennig stamp is clearly cancelled with a circular postmark (Tagesstempel), signifying a 'used' postal status. Condition is assessed as fair; while the printing registration remains sharp, I noted visible edge wear and slight fraying at the top margin, likely due to storage or mechanical handling. From a market perspective, philatelic material from this era was produced in relatively high quantities. While thematic bobsleigh and Winter Sports topicals have a steady niche audience, the market is currently saturated with used specimens. Comparables for this specific Altenberg sheet typically realize low single-digit prices at auction. In mint never-hinged (MNH) condition, the value would be slightly higher, but the heavy cancellation—while desirable for certain 'fine used' specialists—generally caps the value for general collectors. The primary value drivers here are the topical interest and the historical significance of the Altenberg track. However, the condition issues mentioned significantly limit its premium. Note that this appraisal is based on image analysis alone. Without a physical inspection, I cannot verify the integrity of the gum on the reverse, the presence of hidden thins, or the authenticity of the cancellation ink. A definitive authentication would require checking for the correct fluorescence under UV light and a physical measurement of the paper density and perforation gauge to rule out high-quality reproductions.
