This round medallion is held by someone in the trailer. It looks familiar but I can't place it.
Is it something from existing Star Wars lore?

It looks very much like one of the medals Leia gives out at the end of A New Hope. Whether it's Luke's, Han's, or someone else's, we don't know, but the similarities are pretty apparent.
The image from the trailer doesn't look as "clean", i.e. it's obviously hand-made, while the replica is obviously machine-made, but they're clearly intended to be the same medal.
