Our stamp business began in 1980 as a part-time endeavor and became full-time upon retirement from the U.S. Army in 1995. Our goal has been to provide collectible stamps at a reasonable price.
In addition to Allstamp.net, we buy and sell at 25-30 west coast shows annually. We also sold stamps on eBay from 1999 through 2009.
We do shows as Martin Shupe Stamps, and focus on United States and German stamps and covers, but always have a great selection of other countries for our customers.
We belong to the American Stamp Dealers Association,the American Philatelic Society and the Germany Philatelic Society.
