Which is correct? I haven't the foggiest idea about it, as my research has been able to find no such question anywhere.
- The crystal found yesterday by me costs dozens of euros.
- The crystal found by me yesterday costs dozens of euros.
Which is correct? I haven't the foggiest idea about it, as my research has been able to find no such question anywhere.
Both forms seem somewhat clunky to me.
How about:
The crystal I found yesterday cost me dozens of Euros
or (if you found this crystal as opposed to buying it):
The crystal I found yesterday is worth dozens of Euros
These wordings remove any ambiguity about how you obtained the crystal and describes the nature of its value.
