Silver Shield worn by Chief Petty Officers

From left to right: - Miniature lieutenant junior grade pin-on rank - Miniature Coast Guard cap device - Coast Guard cap device in bullion version

The officer's cap device for the service cap consisted of a large spread eagle with shield holding a fouled anchor in its talons.  A miniature cap device was worn on the left front of the garrison cap while a miniature pin-on rank was worn on the right front of the garrison cap.

Chief Petty Officers had a special cap device which consisted of a fouled anchor with the Coast Guard shield in the center. A miniature version of this shield was worn on the left front of the garrison cap. While enlisted SPARS wore a black band with "U.S. Coast Guard" in golden letters on their service cap, a collar insignia (as shown below) was worn as cap device on the left front of the garrison cap.

SPARS Collar Insignia

The collar insignia worn by all SPARS was a miniature Coast Guard seal in gold metal. It consisted of a circle over two crossed anchors. On the circle, the letters "United States Coast Guard 1790" were embossed. In the middle was a federal shield with the letters "semper" at the top and "paratus" at the bottom, the motto of the Coast Guard.

Enlisted personnel wore navy blue plastic buttons on all service jackets. SPARS officers wore the navy blue plastic buttons on the gray working uniform only. Otherwise, they wore gilt buttons on their service uniforms.

1st Class Seaman patch

SPARS with the rating of Apprentice (or 3rd Class) Seaman wore a single diagonal white stripe (on blue uniform) or navy blue stripe (on white and gray uniform). SPARS with the rating of 2nd Class Seaman wore two diagonal white stripes (on blue uniform) or navy blue stripes (on white and gray uniform). SPARS with the rating of 1st Class Seaman wore three diagonal white stripes (on blue uniform) or navy blue stripes (on white and gray uniform).

The rating badges of Petty Officers consisted of an eagle, specialty mark and chevrons. The eagles and specialty marks were embroidered in white on blue backgrounds for blue uniforms.  On all other uniforms, the eagles and specialty marks were navy blue on a background corresponding to the uniform color. The chevrons were scarlet for the blue uniforms and black for all other uniforms.

..

Specialist ratings were worn as part of the rating badge by women enlisted for special service. Specialty Marks were an indication of skill attained in a particular field. While Distinguishing Marks were also an indication of skill, they were never worn as part of the rating badge. It was possible to earn a Distinguishing Mark without having advanced beyond the non-rating badge. Several of the Specialty Marks and Distinguishing Marks were identical in design. 

The table below shows a couple of Specialty Marks 
(some of these were also used as Distinguishing Marks).

Sleeve stripes indicated the rank of officer's on jackets. Instead of golden sleeve stripes, SPARS officers wore blue stripes on their jackets (navy blue stripes on white and gray uniforms and reserve blue on blue uniforms). This difference to male officer's uniforms should point out their status as reserve.

The rank table shows the ranks that could be obtained by SPARS officers prior December 1943.  The highest rank of Lt. Commander was allowed to be held by one person only. This one person was Ms. Stratton, director of the SPARS.

.
In December 1943, SPARS officers were granted two more ranks, the one of captain and commander. These additional ranks were indicated by four thick stripes (captain) and three thick stripes (commander). Like before, the highest authorized rank was allowed to be held by one person only.
.

Pin-on ranks had to be worn on both sides of the collar on the working dress and on shirts if the jacket was removed.  A pin-on rank was also worn on the right side of the garrison cap.

Service Stripes

.v

One service stripe sewn to the lower left sleeve indicated 4 years of active service. The lower edge of the stripe should not be less than two inches from the bottom edge of sleeve.  The stripes were scarlet on blue uniforms and navy blue on white and gray uniforms. Since the SPARS started their service in December 1942, there were no service stripes worn by SPARS during wartime.
