      Re:  First Cash Financial Services, Inc.,
           Registration Statement on Form S-8

 Gentlemen:

      We have represented  First Cash Financial Services,  Inc.,  a  Delaware
 corporation   ("Company"),  in  connection   with  the   preparation  of   a
 registration statement filed with the Securities and Exchange  Commission on
 Form S-8 ("Registration  Statement") relating  to the  proposed issuance  of
 1,800,000 shares ("Shares") of  the Company's common  stock, par value  $.01
 per share ("Common Stock") issued pursuant  to a certain agreement  ("Plan")
 attached as an exhibit to the Registration Statement.

      In  this  connection,  we  have examined originals or copies identified
 to our satisfaction  of  such  documents,  corporate   and   other  records,
 certificates, and  other  papers  as we  deemed  necessary  to  examine  for
 purposes of  this  opinion, including  but  not  limited  to  the  Plan, the
 Certificate of Incorporation of the Company, the Bylaws of the Company,  and
 resolutions of the Board of Directors of the Company.

      We  have  examined  such  records  and  documents  and  have  made such
 examination  of  laws  as  we considered  necessary  to  form  a  basis  for
 the opinion  set forth  herein.  In  our examination,  we  have  assumed the
 genuineness of all signatures, the  authenticity of all documents  submitted
 to us as originals, and the  conformity with the originals  of all documents
 submitted to us as copies thereof.

      We are of the opinion that the Shares will be, when issued pursuant  to
 the Plan, legally issued, fully paid, and nonassessable.

      We hereby consent to the  filing of this Opinion  as an Exhibit  to the
 Registration Statement.


                                    Very truly yours,


                                    /s/ BREWER & PRITCHARD, P.C.
                                    ----------------------------
