ISGC Benefit Auction 2024

Bids for the 2024 ISGC Benefit Auction closed on April 30, 2024, and the auction was finalized during the first week of May 2024. The auction uses lots donated by members of the ISGC and is administered by volunteers. All the proceeds of the auction go to the ISGC to benefit its members. The auction was announced in the March 2024 El Quetzal and all lots were listed on the ISGC website. The donated material was divided into a total of 43 lots. All of the lots offered in the 2024 ISGC Benefit Auction were sold, for a total of $1,550.00 USD. 100% of the net proceeds from this auction go directly to our society. There was some spirited bidding on a few of the more popular lots, and three of the lots had tie bids, with the earliest bidder winning the lot. 

We extend profound thanks to the ISGC members who donated material for this auction: Bob Lebow, James Mazepa, Tobias Tomlinson, Ariel Dominguez, Orlando Gamero, David Gooder, Barbara Vignola, Roberta Palen, and Glen Carr. These generous donations keep the society operating to provide a common gathering place for Guatemala philatelists.

Guatemala Fakes and Forgeries

Collecting the stamps of Guatemala is an interesting and potentially complex challenge, and collectors of the country are helped by a large body of available information. Previous El Quetzal editor and former International Society of Guatemala Collectors (ISGC) president David Reitsema has added to this information by writing these articles to assist ISGC members and other ISGC website visitors distinguish between genuine stamps and fakes.

Member Download

Long-time ISGC member Jack Jonza  collected nearly 150 articles and clippings that have information of interest to Guatemala collectors. The articles come from many sources, including magazines that have not been published in many years. These have now been scanned and indexed, and may currently be viewed and downloaded in the Document Library (Non-ISGC Articles in the Non-ISGC Publications folder) by members after logging in. The first PDF in the folder (Jonza Documents Contents) was prepared from a spreadsheet containing information on the documents, including author, publication, publication date, catalog numbers, etc. Download it, then use the links in the titles to go to the individual documents that interest you.
