The current price for a forever stamp is .44 cents (2010) so 20 years from now the value of that same stamp will still be .44 cents, even if the price for one ounce is $2 then. So, you would need five forever stamps from this year for 1 ounce in 20 years.
If you have other stamps than just just the .44Â¢ Forever Stamp, you could use three (3) Forever Stamps, 3 x .44Â¢ = $1.32; and then make up the difference with .08Â¢ more postage.
