Information printed on stamps varies enormously from country to country and even within some countries. There are two things a postage stamp will have as a minimum based on the IPU requirements: 1) an indication of country of origin - this is most commonly shown by the country name appearing on the stamp but in a few cases it may be indicated some other way. For example British stamps have no country name but incorporate an image of the reigning British monarch into the design of every stamp. 2) a postal value - i.e. a figure indicating the amount of postal credit you have purchased. If there is no postal value, it is quite possible what you have is not a postage stamp at all.
I believe you are referring to the G Make up rate stamp. Issued in 1994 it has a face value of 3 cents.
That will depend a great deal on which 15 cent stamp it is. There have been stamps issued for many decades with that value. Consult a catalog and identify the specific stamp. It will also help you find the value.
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¢.
There were many of these notes taken to the post office to get a stamp and a first day cancel seal -- they are not rare. In a nice holder, it has a retail value of $3 to $4.
This stamp is a semi-postal stamp which means it sells for more than face value and the extra amount collected goes for research towards finding a cure for breast cancer.When postage rates went up, rather than coming out with a new stamp, they justraised the charge for the stamp. It is still worth first class postage, now 45 cents, regardless of when you may have bought it, if it is mint.Used, your stamp has negligible value ( less than 10 cent retail) , but please do not throw it away! Keep it in your stamp collection for your children or yourself when you have more time. If you have more than one,you may be able to trade it for stamps of similar value. Or give it to a collector friend. Collectors always appreciate the thought even it they do not need the stamp.
