I dunno. . . . I'm still not comfortable with the idea of an artifact attracter artifact - even an artifact sonar. Of course, I don't have the final say, so maybe Draco is alright with the idea (he does have his incomplete artifact theory). I will say that the sonar is more likely than the attracter.

Actually. . . . That gives me an idea. While its true we've never seen an artifact detector which is an artifact, we HAVE seen an artifact detector. The Artifact Tracker Football (you can see it on the main wiki, link here) is more of a gadget than an artifact, and it tracks artifact activity around the world and sends the Warehouse pings when one activates. Now, what if the coin (or perhaps a different object) has some artifact-sonar effect, but more in the sense of a gadget than an actual artifact? Something more limited in functionality, like say "activates in an X-mile radius from active artifact", and we keep the downside you suggested (magnetic interference)? It's up to you. If you'd rather pursue the artifact track, just run it by Draco to make sure it doesn't interfere with any established continuity here, as I'm not familiar with that field.
