The top one is the reverse of the coin representing the U.S. Coast Guard Chief Warrant and Warrant Officer Assoc. The other two represent the Juneau and Rocky Coast (New England) local clubs of the Association. The club coins are ringed with all of the warrant officer specialities availalble in the Coast Guard. The other side of the club coins has the 3 warrant officer bars also.
The Coast Guard immediately promotes to permanent W-1/temporary W-2 thus the absence of the W-1 bar on the coins.
