Consider using regular expressions to do your matching: 

my $string = 'PARJT$$';

if ($string=~m/\$\$$/) {
 print "match";
}

The backslashes are used to literally match the $ which otherwise is interpreted as the special character which represents the end of the string. We use a bare $ later to show we are only looking for matches at the end of the string.
