[quote="jakelomas"]well I went to America a few months ago and got some stamps (Navajo Jewelry 2c Stamp A Wisom Rockefeller Center 1 Dollar stamp and 2 44c Black Heritage with Oscar Micheaux stamp ) well would I still be able to use these as I got them a few months ago and how much does airmail cost for a 1.7 Ounce letter if I have 1.00 worth of stamps (that is what those stamps will equal) please help[/quote]
If it is a letter [u]sized[/u] envelope, then yes, $1.82 will cover that. If I added the value of the stamps correctly, you have $1.90 total postage, which will cover that. (.02+1.00+.44+.44=1.90)

Here's the link to postage prices for sending outside the US. It's pretty straightforward, but if you have any trouble figuring it out, let me know.

$1.82 from the US to the UK....stamps never lose their value, they just keep raising the rates.
