Without any photos of your coin there is nothing that we can tell you except that you should not attempt to clean or "improve" the coin. If you want feedback on your specific coin post some photos, as you say your found it in your change the chances are very high that the coin is only worth face value.
Some general info: The mint coined 800,953,300 1958-D cents, these are not rare unless in exceptional condition (coins found in change are not in exceptional condition) and there are two recognized doubled dies for 1958-D cents. Here is a link to a site that lists the two recognized doubled dies, and while not likely, you can see if your coin is a match for either.
