You are buying a custom made Police Hat Challenge Coin. One side has a thin blue line in the middle (and the words "Sometimes There's Justice" "Sometimes There's Just Us" on it. The letters are in a gun metal grey color. The other side is actually two toned (hard to tell in the photo). The top of the hat is a dark navy blue and the visor portion is black. The police badge on that side is also a gun metal grey color. You can see the colors more clearly on the last two photographs. The Coin is 2 inches in length and 1.25 inches in height.
I have several challenge coins up for auction so please check them out at my ebay store. None of these coins were personally given to me. I buy coins from a variety of sources (personal collections, wholesalers, manufacturers, etc.).
