In Great Britain it was one cent in 1840 when the were first issued. In the US, postage has never been one cent. The lowest rate has been 2 cents for an ounce of mail.

For US postage, that answer is absolutely incorrect IF we are still talking about post cards, as the page containing the link to here from the previous page stated. Post card postage on a government printed card was one cent beginning in 1893. IF we are now talking about first class mail or its early equivalent, (first once) then the above answer may be correct.

Yes, but that would be foolish. Buy some one-cent stamps to make up the 42 cent postage and save those 41 cent stamps.
There was a sheet of 33 cent baseball heros stamps that included one of Lou Gehrig. Other countries have issued stamps, St. Vincent issued one about 1992.
One .42 cent stamp
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.
Postage stamps that are worth 32 cents can still be used but they must be combined with other stamps to meet the current postage rate. In January of 2014 the current postage rate was 49 cents for a letter that weighs one once of less.
US stamps come in different denominations, but if you just asked for a stamp you would probably get a 44 -cent stamp which pays postage on a letter of up to one ounce. The "forever" stamps currently are considered to be 44-cent denomination.
The total number of stamps doesn't matter as long as they make a total of 61 cents of postage. You can use one 61 stamp, or a 44 cent with a 17 cent stamp. Or you can use 61 one cent stamps.
Stamps are always and forever worth the denomination printed on the stamp. If you need a one-cent stamp to complete postage, and you have a one-cent stamp from 1933 - it is perfectly legal. As to what individual stamps are worth to stamp collectors - that is a completely different question.
If they say 42 cents on them, you need the additional 2 cent stamps to make up the difference. If they are 'Forever' stamps, they are valid for one ounce of First Class Postage regardless of the cost.
In Great Britain, the stamps were 1 cent. In the US postage was 5 cents for the first half ounce. They weren't available in the US for several years after that before they were issued.
