I am assuming you are talking about a US stamp and want to use it for US postage.
You can, if i it s uncanceled. Of course, it only pays for 27 cents in postage, so you would have to add enough other stamps to pay the required postage for whatever you are mailing. The post card rate is now 28 cents, so you would have to add a 1-cent stamp if you want to use it on a post card.
Maximum size for a .27 stamp is 4 inches by 6 inches. Anything over that size will be classified as "letter" and requires the full first class postage stamp.
Postage never was 27 cents in the US. From April of 1988 to February of 1991 it was from 25 cents. Then it went to 29 cents for the first ounce.

Yes there is. The 'G' Stamp was a 32 cent stamp and was issued because of the rate change from 29 cents to 32 cents in 1994.

41 cents is 1 cent short of the required 42 cents. What happens depends on your luck. It may go through with no problem. It may be sent back to you canceled - you would need another 42 cent stamp to mail it -- or if it is caught near where it is to be delivered they will try to collect 1 cent from the receiver.
