it may be old news, but i came across this today.
taken from Cadalyst Newsline: News and Productivity Tips for CAD Users

8. TIP FROM AUTODESK: FIND A FILE'S PARENT AUTOCAD VERSION
To determine the version of AutoCAD that created a particular DWG or
DXF file, open the file as a text editor (save DXF files in ASCII
text format first). The first six bytes of a DWG file identify its
version. In a DXF file, the AutoCAD version number is specified in
the header section. The DXF system variable is $ACADVER. Here are
the version identifiers for the various releases. Note that more
than one release uses the same identifier when the drawing format
remains fully compatible.
AC1018: AutoCAD 2004
AC1015: AutoCAD 2002, 2000i, 2000
AC1014: AutoCAD Release 14 (Release 14 sample drawings use AC1013)
AC1012: AutoCAD Release 13
AC1009: AutoCAD Releases 12, 11
AC1006: AutoCAD Release 10
AC1004: AutoCAD Release 9
AC1002: AutoCAD Release 2.6
AC1.50: AutoCAD Release 2.05
