2011
The US offers 5 cent stamps. They can be used to make up the difference with older stamps. Or to complete the cost for packages. You may have to order them through the USPS, not all post offices will have them.
In the US the 29 cent rate lasted about 4 years. Several hundred stamps were issued during that time. In used condition there is limited value, you can purchase them for about 20 cents each. Which means a dealer is not likely to pay much for them unless you have a large number of them.
That will depend on the value of the stamps you have. If you have one cent stamps you will need 190 of them. If you have ten cent stamps you only need 19.
