From my recent observations, there are less people interested in geese stamps internationally nowadays. However, geese covers are still hot. This may be partially due to a few mainland collectors are chasing the geese covers.
I have not seen 2nd or 3rd print $50 covers for a long time except some parcel posts. There are only 3 1st print $20 covers known to exist so far.
I had one geese cover that may have lost in the mail recently................well, according to USPS tracking, the registered cover stuck at New York custom for more than a month and USPS told me that "Be patient, it may take much longer than a month"......lots of BS for an air mail item!. Now I'm more interested in the cover that was supposed to arrive 3 weeks ago than the geese cover.
