ITEM 7.01.  REGULATION FD DISCLOSURE

         Upon authenticating and assigning a numerical quality grade to a coin,
Collectors Universe's coin authentication and grading subsidiary, PCGS, issues a
certificate that confirms the authenticity and sets forth the numerical quality
grade assigned by PCGS to that coin, which signifies that the coin is a PCGS
"certified coin". In the ordinary course of our business, we maintain and
regularly update a database of (i) the total number of coins that PCGS has
certified, classified according to the different numerical quality grades that
PCGS has assigned to those coins, and (ii) a cumulative total of the number of
coins that have been certified by PCGS since it commenced its coin
authentication and grading business in 1986.

         The Company has begun publishing on its website, at
http://www.pcgs.com/poptotal.chtml, a summary "population report" which sets
forth such information, in tabular form. We also will update that report on a
weekly basis for additional coins that we certify.

         The population report also happens to contain data that make it
possible to determine the number of coins that PCGS has certified in any
specific time period (such as a month, a fiscal quarter or an entire fiscal
year), by subtracting the cumulative total of PCGS certified coins shown in the
population report at the beginning of that time period from the number at the
end of that period.

         However, it is important to recognize that the number of certified
coins shown in the population report may include multiple certifications for the
same coin, as coins are often submitted to us for certification multiple times,
each at a different time (largely dependent on the number of times the coin is
listed for sale or bought and sold).

         Additionally, there are coins that we examine and process which are not
assigned a numerical quality grade and, for that reason, are not included in our
summary population report, even though we generate revenue from processing them.
For example, ordinarily we do not assign a quality grade to coins that we find,
upon examination, to have been damaged or be have significant imperfections. We
also sometimes receive bulk coin submissions for processing, for which the
submitters request the assignment of a more generic grade, such as
"uncirculated," rather than a numerical quality grade. Consequently, the total
number of coins that we certify, and that will be included in the totals set
forth in our population report, for any given time period, ordinarily will be
less than the total that we will have examined and processed and, therefore,
that will have generated revenues for us, in that time period. Moreover, the
number of uncertified coins that we process varies from period to period.

         For these reasons, it will not be possible to use population reports to
reliably determine the number of coins actually processed by us during any time
period or to determine trends in the volume of coins we are processing or are in
our reported coin authentication and grading revenues.

         In accordance with General Instruction B.2 of Form 8-K, the information
in this Current Report on Form 8-K, including Exhibit 99.1, is being furnished
and shall not be deemed "filed" for purposes of Section 18 of the Securities
Exchange Act of 1934, as amended, or otherwise subject to the liabilities of
that Section, nor shall it be deemed incorporated by reference in any filing
under the Securities Act of 1933, as amended.
