How much are Mexico olympic stamps worth?

Answer 1

You will need to consult the catalogs. There are many Olympic stamps issued by many countries commemorating the Olympics in the various locations, including Mexico. Most libraries will have a copy of Scott's Postage Stamp Catalog of the World. First of all, you have to identify the specific stamp or card. That in itself can be a daunting task, but most of the catalogs are well illustrated with lots of information. Once you know what item you have, the catalog will provide a set of prices that can be used to estimate value.
