I'm not sure about all of them, but I am sure the ones on the left, top three rows, three in are all new. I used them before the price hike. Also the forever stamp and the 2 cent stamp are fine. The others, you would have to ask someone who knows about stamps. {thumb2}

agreed. alot of those stamps look like collectibles that may b worth money. id stick to new age stamps and keep those

Stamps dating back to 1861 can still be used today, though I wouldn't bother using old stamps simply because they become valuable and collectible.

As jdp3577 said, those are fine to use. I don't know of any stamps that expire after a while so as long as the right amount is on the envelope, the post office won't care what denomination of stamps they are in.

yes you can use those, the value is printed on the stamps, you have quite a few 90 cent ones and an assortment of other values

Are these stamps Ok to use to send requests? I don't know how hold they are or the value, so I just want to make sure.
