ISGC Benefit Auction 2026


Our next Benefit Auction is scheduled to be held in the 1st Quarter of 2026. Lots are now available for viewing. Bidding information is forthcoming. 

100% of all net proceeds go to the ISGC to help support our society!

Minimum Bids for each lot are listed on the 2026 ISGC Auction Listing. Scans of the 2026 ISGC Benefit Auction lots have been uploaded.

A DOUBLE BENEFIT FOR OUR SOCIETY: Our previous ISGC President, Michael Bloom, has offered to donate the equivalent value of all winning bids for this auction. This will double our expected net income for this activity. Thank you to Michael for his generous offer.

----------------------------------------------------

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. Click here to see the articles and a taped presentation on YouTube by David.

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. 

El Quetzal

Richard Eldridge assumed duties as the editor of El Quetzal, starting with issue #396. A PDF of the entire March 2017 issue has been made accessible on-line to the public to serve as an example of what is available to members.
The cover of the current issue of El Quetzal, #404, December, 2025, is available for viewing. Members may sign in to view the entire issue online in the Library section of this website. All past issues are also available to members.
