For example, the original photo is named "scene-Radnor-con30" and the duplicate is named "scene-Radnor-con30 - Version 2". Other than manually deleting each one, I have also used an app called PhotoSweeper, but with not great results. I have 50,000 photos, half of which are dups.
Thank you.

Has this Library ever been opened with Aperture?
No. I don't use Aperture yet. I have used Picasa, but recall I stopped before this issue came up. The dups are all in the same event too.
How were these duplicate photos added to the library originally?
If by external import try using the free application iPhoto Duplicate Cleaner. I found it works very well.

In the latest version PhotoSweeper has updated Media Browser. Now it has a search field, which can help you to filter your photos. You can select in popup menu "Version Items' to see only ".. - Version 2" files. Then select all of them and move to trash right from this Browser.
Warning - there have many reports of PhotoSweeper trashing iPhoto libraries - I hav not personally tested it but if you are going to use it be very carful and be absolutely sure you have a great backup
Based on reports I would recommend against usint it

I've never had problems with PhotoSweeper. Maybe there were some issues in past, but now it works fine. Also I read many positive reviews from users, and "Based on reports" I would recomend it everyone who want to remove duplicate photos from their libraries.
I'd suggest you to test PhotoSweeper before suggesting not to use it. There is a demo version of this app.
Duplicate photos in iPhoto, all with "- Version 2" added to original name. For example,
