There are several good ways to track down high quality stamp dealers.
The good news is that once you have found a couple of good stamp dealers, you can normally depend on them for excellent service for years to come.
One of the first things you will need to do is browse the online auction site, eBay, for stamp selling and philatelic stores. Pay particularly close attention to the feedback rating of each store and whether or not it is a “power seller”. Power seller status is awarded to the most popular, reputable and successful stores.
A second approach is to browse your local telephone directory for brick-and-mortar stamp collection shops in your area. You may not have one on your closest main street but if you live in a big city you will almost certainly have access to at least one very useful store.
If you still can’t locate a stamp dealer that you are happy to use, get in touch with the local philatelic society and ask for some recommendations. The philatelic society may include members who sell a number of stamps, and the society itself can be a great place to meet people who are willing to trade and sell stamps.
