Wow, nerds, pay attention to how is done. Wait for a syndicate mission Def/Int on either Corpus Snow tileset or Grineer Galeon tileset. These missions spawn medallions and you can pick'em up before starting the mission. Some of these spawn enemies before the mission starts so keep that in mind. The corpus mission spawns 6 medallions, the grineer one spawns 8. Collect all the medallions in the mission and abort. Enter once again and complete the challenge (think max is 17 medallions). Aborting doesn't affect the count.

Incidentally this is the fastest way of completing this challenge, you can do it in under 3 mins with the right conditions.
