Metal sliver in oil -- time to panic?

I was doing my first oil change on my new-to-me MKIII when I noticed a small sliver of metal sticking to the magnetic sump drain plug.

The piece is ferrous and fairly stiff. No glitter in the oil or any other pieces I could find. Engine seems to run fine.

Any ideas what this might be and how worried I should be about it?

A single piece on its own is not giving much information. Its now a watch and see, so check the magnet frequently.

Some better quality close up pictures, taken from different angles, may also help people to identify the mystery object… your current picture shows little more than a grey shape when zoomed in…

Bearing cage?

Possible, but is it an old piece left inside during the last rebuild or a piece from a newly fitted bearing. Need to know the history of the bike, ie was it sold as just having had a rebuild (a red flag IMHO) or one with a decent amount of miles since the rebuild.
