You GMs might have some fun with this random generator I put together. They aren't really treasures, but more like random items. Some of them are valuable, some of them are junk, some of them are really useful, some are intriguing. When you click the "Generate" button, you'll get 5 randomly selected items from the list of over 18,000 entries.

This generator might give you ideas for adventures, or help you out when your PCs start looking for loot. Hope you find it useful.
I'm always looking for new items to add to this list, so if you've got any suggestions, just let me know.
