Barber's nickel design. This is one of several patterns for this year using different alloys of nickel and/or copper showing their composition on the reverse within the wreath.
2 or 3 dozen are known. Pollock gives weights of about 78 grains for these. It is likely that some of these were struck on standard nickel planchets of 25% nickel and 75% copper.
Examples were also struck in aluminum J1713/P1917. About half a dozen are known.
