Alderfer’s January sale spans Zeppelin issues, classic United States covers and worldwide rarities

Alderfer Auction held an online United States and worldwide stamp sale ending 20 January. Highlighted categories included Zeppelin stamps, a Falkland Islands Centenary set, classic United States numbers 1 and 2 on cover, Colombian postal currency and early Confederate covers.

International material advertised by the auctioneer included Great Britain and German souvenir sheets, alongside broader country collections, singles and sets. The range makes the catalogue useful not only to bidders but also to collectors researching how specialised air-post, classic-cover and never-hinged material was described and grouped in early 2026.

Auction descriptions should be checked against high-resolution images and certificates. Phrases such as “investment-grade” express the seller’s positioning and are not a guarantee of future value. Buyers need to include premium, tax and delivery in total cost, while researchers using results should note whether a lot sold, passed or contained mixed material.
