There is a discrepancy in the Jeppesen's 10-9 related to DEN. While the mag variation has shifted; the airfield diagram does not reflect the new magnetic runway headings for the [runway]. The diagram indicates the mag heading as 173/353 for all north/south runways. However; if the info page is selected; the runway headings are 172/352. While the difference is not significant; it is a discrepancy that needs to be corrected to avoid potential flight safety issues. A similar issue exists for the east/west runways. RWY 8/26 is 082/262; but the 10-9 says 083/263; while 7/25 is 082/262; but the 10-9 shows 082/263. Lack of attention to detail. Develop a system at Jeppesen to identify mag variation shifts beyond simply those that require runways to be renumbered.
ERJ First Officer reported  the DEN Jeppesen 10-9 airfield diagrams do not correlate with the magnetic variation change.
