3/5     For the "First Class" stamps which I bought for $0.33 but which don't
        have "33 cents" printed on them, does it mean I can still use them now
        34-cent stamps?  Thanks.
        \_ If you post a letter with 33c instead of 34c, the post office
           will probably still deliever it, but they are under no obligation
           to do so. I wouldn't send any bills that need to arrive in a
           timely fashion with just a 33c stamp on it.
           If you want to be on the safe side, buy some 1c stamps and add
           them to your letters.
        \_ I have sent exactly 1 under-posted letter out and got exactly
           1 under-posted letter returned for more postage.
        \_ No; they were first class stamps when they were printed, but their
           first-classness has been superseded now that there's a newer series
           of non-denominated first-class stamps.  They're worth whatever the
           first class rate was at the time they were printed (part of the
           reason they started printing the year on stamps a while back).
           \_ I just bought some first-class stamps (no value printed) from
              the post office a few days ago for $0.34 each, but there are
              "2000" printed on them.  Does that mean I got cheated and they
              are only good for the first-class rate last year?
        \_ why does the PO make stamps that don't have the value printed on
           them?  it's silly.  is it just so that they can print the stamps
           before they decide on new rates?
