About CGO's Professional Version
The Professional Version of Visual Guide to Auction
Prices provides you an unique and valuable tool where
you can
view and compare realized auction prices from over 10 different auction venues.
Whether you are a collector or a dealer, this powerful
investment tool alone can potentially save you hundreds of dollars.
With the Professional Version, you can readily see,
for a given grade, which auction venues would fetch you
higher prices for your lots and which venues would net you
lower prices for your purchases.
Professional Version has ten auction-venue
categories listed below its X-axis (with the 10th one being the catch-all
"Others"). Each auction venue has its own graph line plotted for a given
BG variety. You can click on any auction-venue's check box to toggle off and on
its associated graph line for a better view of data.
As is the case with the standard version, you can view the graph lines in one
of the two modes: Accumulative or Time-sensitive. With the
Accumulative mode, the number of auction sales is marked along its X-axis. With
the Time-sensitive mode, auction sales are plotted along the X-axis based on
their sale dates as a percentage of time elapsed from the date of the 1st sale
to the last known sale date of a given BG variety.
The Professional Version is accessible only from
the standard version of Visual Guide to Auction Prices for "Gold Pro"
subscribers.. In the standard version, you will find, underneath the BG
Number Submit field on the upper-left corner of the display, a "golden" button
that says: "Go to Professional Version."
On the Professional Version,
you will also find another button link. Titled "Graph Creator,"
this link will take you to another web page where you can make your own
selections and literally create over 342,000 different
graphs! Parameters for your selections are, as follows:

California Gold Fractionals (Cals).
They are:
-
PCGS (Professional
Coin Grading Service)

NGC (Numismatic Guaranty
Corporation

ICG (Independent
Coin Grading Company)
Of
course, you can always choose "All"
to view data for all grading
companies.
Grade
For
this parameter field, you can
select one of the grades from
"MS-67" to "Below VF-35" or the
catch-all "All."
Rarity Value
Values for this parameter field
goes from R-9 (unique) to R-1
(over 1,250 known). There
are 18 different parameter
values, including "All."
Price Range
For
this field, its parameter values
sometimes change - depending on
the type of graph report
selected. After you make
the selection for the Price
Range, check the current setting
on the left side for a short
description of your choice.
After
making your selections (one at a
time), you will be given a graphical
display, showing data points - for
each of the thirteen groupings of
Cals, from 1xx to 13xx, covering all
the three Periods. Imagine
being able to see, inside of one
screen display, the "whole
picture" of Cals in an instant!
Happy
diggin'!
