How do I get a rough idea of what my stamps are worth ?

     Collectors can make an appointment for a free consultation. We can usually provide a rough idea of your collection’s value.

     Alternatively, most libraries have stamp catalogues where you can inventory your collection and look-up the value of each individual stamp. Remember that the market value, or the price which you can sell the item for, is often a fraction of the catalog value.

Why doesn’t Harmers advise on the use of stamps as an investment?

     The value of a stamp is based upon market conditions. Many factors including market condition, affect a stamps value. There are many more predictable instruments, such as stocks, that are more appropriate for investment. We focus our efforts on the collector.
