Here is a website that shows all the "nondenominational" stamps that have been released. The do have a certain value and this chart is handy to keep around. http://pe.usps.gov/text/qsg300/Q604a.htm
What stamps? First postal stamps were used in 1840.
Semi-postal stamps are those sold at more than their postal value, with the additional money going to the specified charity. The U.S. Postal Service has issued three semi-postal stamps and all of them are still valid as postage. The Stop Family Violence stamp was retired on December 31, 2006 and its postal value is fixed at 39¢.
Go to the USPS web site. You want publication 604a, which shows all of the non-denominated stamps issued by the US Postal Service.
Not really. The total number of stamps will be fixed and it will still depend on the demand for them. And as a general rule over time their value would increase. I don't think there would be a huge spike in value.
All Newfoundland stamps are valid for postal use at their face value because they have not been demonetized (their use denied) by Canada.
The Forever Stamps should not be used for international mail. It does not show a denomination. Universal Postal Union rules say that the value must be shown.
The US has issued a large number of these non-denominated stamps through the years. Postal clerks have a chart which pictures them all and so call tell you the value of each. Sometimes this chart is posted on the wall of the post office.
There are valuable stamps from all over the world, it depends on how rare it is, it may depend on if it has a mistake on it, it depends if its used or never been used, it depends on the shape it's in. There are website you can find that will have the value of stamps along with pictures, I had a bunch of stamps that turned out the only valuable bunch in the whole bag were the ones from the soviet union. Do some research and you will find your answer. Good Luck. Try doing a search for Czechoslovakia stamp values.
The best way is to consult the USPS web site. They list all of the stamps issued without a value. These stamps can still be used for postage at that value, so other stamps have to be added. They can only be used for US addresses.
{| |- | The first step is to identify the stamps. Consult a stamp catalog such as Scott's, which include pictures and descriptions of all the stamps. They typically include a price for the set as well as the individual stamps. It also provides details on identification as well as a description on how stamps are rated and graded. |}
There are many ways one can learn the value of stamps from Japan. One can learn the value of stamps from Japan at popular on the web sources such as Baxley Stamps and Herrick Stamps.
They are not the same stamps. The ones maked First Class were for a specific postal rate, you would have to specify which one. The FOREVER stamps are valid at the first class rate regardless of what it is.
