Can Anyone Identify This Pin?

[ajaj]

Found this metal detecting in an old baseball park. Lots of Mercury and Roosevelt dimes have come from it. I know it's not valuable, but I was looking for any identification and history for the heck of it. I have searched and searched Google and come up with nothing. Now, I know someone here will probably find it right away on the web (analogous to my wife opening a pickle jar after I have struggled "loosening it"). Thanks.

(Analogous- I'd be weary) It could be just a hat pin with a random number like the date.

Bike is a sidecar rig and couldnt connect that with the "82",not sure if represents year or just generic number.Nothing on name either.Not a motorcycle person so hopefully someone will pop up an answer,curious now if it means anything.
