I am using ArcGIS for Desktop and I have a layer that visually appears to have 50 points. However, the attribute table shows 450 rows, indicating that many points are overlapping. I would like to show only 50 unique points (and have the attribute table reflect that). It is not important which of the overlapping points are saved as I need to do a geospatial analysis and the actual attributes in the table are not important (it's only important that there are 50 of them). How do I create a file with only 50 unique points?

If you are looking for the simple diagonal hatch method you mention, this can be achieved by symbolizing the home range polygons as unique categories. First use the '10% Simple hatch' symbol for all, and then customize the individual symbol patches. For each symbol, click on the Edit Symbol button where you can modify this line fill symbol's color, angle and separation (the offset can also help with multiple overlaps). Unless you have more than five overlaps, using these different settings for each home range should give you a crosshatching visualization that can still be easy to read.

To remove duplicates:
You can use the Delete duplicate geometries tool by accessing it via the Processing Toolbox:
Another option is to use the v.clean tool from GRASS and select the rmdupl option:
To remove overlaps:
You can use the Dissolve tool, provided there are common attributes between the original polygon and the overlapping polygon:
As always, you can manually remove them if there are only a handful. You can do this via the Attribute Table, find your overlapping polygons (useful in conjunction with a topology checker to highlight the overlaps) and select the option to delete features.

Use Find Identical (Data Management) to get an Output of the Identical Points if you would like that, this does not delete from the Data.
Use Delete Identical (Data Management) to delete Identical Points from the Data. This alters your input.
