You will notice that some stamps are highlighted. These are the stamps that are internationally recognized. These stamps will have a selling estimate in the footnote of each type based on sales history and scarcity. Occasionally, other stamps will show up in this list if sales information is encountered. This is rather close to a fair sale price. If you have missing sales data please forward it to the host.
