LA Rams Helmet Pin

This pin is used but in good condition. Its approximately 3/4" X 3/4", so it's quite small. I looked far and wide for any info on this pin, only to come up empty-handed. It's a bit thicker than other pins and is actually pretty cool looking. It's kind of hard to explain what I'm thinking, but it's not a flat pin with a picture of a helmet enameled on it. The back is fully closed with no helmet detail, but the front gives it a feel of like it's actually a helmet. I took a photo of what was on the back, but other than that, there aren't any other words or indications of where this pin came from.
