Ciphers Seal

Ciphers Seal, Image supplied by Heather Manwaring.
Found in Connecticut, USA, 17mm, 4.55g.

CIPHERS curved around edge // (E?)U(FF?)A curved downward / Arabic? script (JN)? beneath.

Above is my interpretation of the seal. Could be Giphers - any further ideas will be gratefully received.
