Interesting item found under my driver seat

[MOstang]

I know folks have found this sort of thing under the carpet in their SSP's before. From what I recall paint can lids are what I remember reading about others finding. The attached piece of metal was under the driver seat in my 1989 Minnesota State Patrol SSP. One side is painted in the color of my SSP, Dark Shadow Blue Metallic, and is marked DSO Police. Fun to find.
