Clark... I couldn't agree with you more...
but in the purchasing venues, i.e.
ebay,
Stamp Wants, etc, if you take the time
to go through 499 listings, very few of
the Full Ty I are to be found... and, when
you (do) find them, (by and large) those
inexperienced or unscrupulous sellers (take
your pick) have them listed as 500's, and
the unwary buyers (falsely believing in the
integrity or experience of the seller), buy
them as 500's at face value, given many of
the buyers are either barely aware of the
Ia characteristics (or not at all) and place
blind trust in the listing...
Now... in terms what is (offered) on the
internet, generally, the Full Ty I is far
more scarce in availability than is the Ia,
and therein, my friend, lies the problem,
where it's an easy game of dectipt (tragically)
