Production pins
From Super-wiki
Each year pins are made for the crew of Supernatural. The last two years (for sure, possibly earlier ones as well) were made by Phil Sgriccia[1].
Here are pictures of them by Season:
Season 10
Including the 200th episode pin. Designed by Phil Sgriccia. "stamus contra malam" translates to "we stand against evil".
Season 8
Season 7
Earlier Seasons
Including the 100th episode pin on the left, a 'kick it in the ass' pin between seasons 1 and 2, and a pin on the right which looks like a Season 6 pin.
