Forever Stamps (US)

I am running low on stamps so I want to buy some new ones. Are all the 41 cent stamps good for mailing a first class letter indefinitely? Or is it just the liberty bell forever stamp?

They’ll indefinitely count for 41 cents worth of postage. However, first-class postage for an ounce or less will not always be 41 cents. It’s only the Forever Stamps that will continue to work for the purpose of mailing a standard first class letter without any additional postage.

I believe if the stamp says .41 on it then it’s not a forever stamp. Only the Liberty Bell stamps are currently sold that way.
